Lupus and CRPS

[Sarahkaplan98]

Hello everyone I haven't post before but this last year has been very difficult for me. January 25th it'll be 1 year since I had a life changing slip and fall causing me many injuries including CRPS. I'm in need of some advice if anyone can relate. Due to having lupus ,fibromyalgia ,raynauds , CRPS etc. I am not a lazy person but lately trying to focus, stay awake not to mention pain. I am hoping somebody can relate and has advice on how to reduce pain and increase energy I would greatly appreciate it. Thank you in advance.

Hello - I get some relief by using Deep Freeze pain plasters - there are no drugs just menthol herbs - they do the large patches which I cut in half and put on various parts that hurt. They last 12 hours so help me sleep. They have a gel and a spray which is great in hot weather. Vitamin D and B12 in spray form really helped for energy as does lots of water - at least 4 glasses a day. Best of luck

Hello Cas70, I have CRPS in my hip to my foot on my left side due to a good deal of damage from a slip and fall. Sinve January 25th 2019 I've been fighting to recover and unable to work. Over the last year I've had many treatments and seen lot's of doctors. My family has fought to help me but it's hard to relate to what I'm fighting daily.

Hi Sarah & Welcome!

There may be many people who don’t know CRPS, so I will give a description, which I am sure you already know!

I am sure you aren't a lazy person, but wonder whether this is how others make you feel?

CRPS is very multifaceted & nerve pain, can be very difficult to treat. My recommendation would be to see your GP/Primary Care Physician & ask for a referral to a Pain Clinic. They would be most helpful because of the many aspects to your condition. The anaesthetists are the expert on pain, but they also offer other activities such as physiotherapy & other therapies - including talking to others with the same or similar condition. You may be surprised by how helpful it is to talk to a therapist, especially as you have had a very difficult time.

Please do use this space to describe more about you, if that is what you would like to do!

With good wishes,

Ros

What is complex regional pain syndrome? (CRPS)

Complex regional pain syndrome (CRPS) is a chronic (lasting greater than six months) pain condition that most often affects one limb (arm, leg, hand, or foot) usually after an injury. CRPS is believed to be caused by damage to, or malfunction of, the peripheral and central nervous systems. The central nervous system is composed of the brain and spinal cord; the peripheral nervous system involves nerve signaling from the brain and spinal cord to the rest of the body. CRPS is characterized by prolonged or excessive pain and changes in skin color, temperature, and/or swelling in the affected area.

CRPS is divided into two types: CRPS-I and CRPS-II. Individuals without a confirmed nerve injury are classified as having CRPS-I (previously known as reflex sympathetic dystrophy syndrome). CRPS-II (previously known as causalgia) is when there is an associated, confirmed nerve injury. As some research has identified evidence of nerve injury in CRPS-I, it is unclear if this disorders will always be divided into two types. Nonetheless, the treatment is similar.

CRPS symptoms vary in severity and duration, although some cases are mild and eventually go away. In more severe cases, individuals may not recover and may have long-term disability.

What are the symptoms of CRPS?

The key symptom is prolonged severe pain that may be constant. It has been described as “burning,” “pins and needles” sensation, or as if someone were squeezing the affected limb. The pain may spread to the entire arm or leg, even though the injury might have only involved a finger or toe. In rare cases, pain can sometimes even travel to the opposite extremity. There is often increased sensitivity in the affected area, known as allodynia, in which normal contact with the skin is experienced as very painful.

People with CRPS also experience changes in skin temperature, skin color, or swelling of the affected limb. This is due to abnormal microcirculation caused by damage to the nerves controlling blood flow and temperature. As a result, an affected arm or leg may feel warmer or cooler compared to the opposite limb. The skin on the affected limb may change color, becoming blotchy, blue, purple, pale, or red.

Other common features of CRPS include:

changes in skin texture on the affected area; it may appear shiny and thin

abnormal sweating pattern in the affected area or surrounding areas

changes in nail and hair growth patterns

stiffness in affected joints

problems coordinating muscle movement, with decreased ability to move the affected body part

abnormal movement in the affected limb, most often fixed abnormal posture (called dystonia) but also tremors in or jerking of the limb.

What causes CRPS?

It is unclear why some individuals develop CRPS while others with similar trauma do not. In more than 90 percent of cases, the condition is triggered by a clear history of trauma or injury. The most common triggers are fractures, sprains/strains, soft tissue injury (such as burns, cuts, or bruises), limb immobilization (such as being in a cast), surgery, or even minor medical procedures such as needle stick. CRPS represents an abnormal response that magnifies the effects of the injury. Some people respond excessively to a trigger that causes no problem for other people, such as what is observed in people who have food allergies.

Peripheral nerve abnormalities found in individuals with CRPS usually involve the small unmyelinated and thinly myelinated sensory nerve fibers (axons) that carry pain messages and signals to blood vessels. (Myelin is a mixture of proteins and fat-like substances that surround and insulate some nerve fibers.) Because small fibers in the nerves communicate with blood vessels, injuries to the fibers may trigger the many different symptoms of CRPS. Molecules secreted from the ends of hyperactive small nerve fibers are thought to contribute to inflammation and blood vessel abnormalities. These peripheral nerve abnormalities trigger abnormal neurological function in the spinal cord and brain.

Blood vessels in the affected limb may dilate (open wider) or leak fluid into the surrounding tissue, causing red, swollen skin. The dilation and constriction of small blood vessels is controlled by small nerve fiber axons as well as chemical messengers in the blood. The underlying muscles and deeper tissues can become starved of oxygen and nutrients, which causes muscle and joint pain as well as damage. The blood vessels may over-constrict (clamp down), causing old, white, or bluish skin.

CRPS also affects the immune system. High levels of inflammatory chemicals (cytokines) have been found in the tissues of people with CRPS. These contribute to the redness, swelling, and warmth reported by many patients. CRPS is more common in individuals with other inflammatory and autoimmune conditions such as asthma.

Limited data suggest that CRPS also may be influenced by genetics. Rare family clusters of CRPS have been reported. Familial CRPS may be more severe with earlier onset, greater dystonia, and more than one limb being affected.

Occasionally CRPS develops without any known injury. In these cases, an infection, a blood vessel problem, or entrapment of the nerves may have caused an internal injury. A physician will perform a thorough examination in order to identify a cause.

In many cases, CRPS results from a variety of causes. In such instances, treatments are directed at all of the contributing factors.It is unclear why some individuals develop CRPS while others with similar trauma do not.

How is CRPS treated?

The following therapies are often used:

Rehabilitation and physical therapy.

An exercise program to keep the painful limb or body part moving can improve blood flow and lessen the circulatory symptoms. Additionally, exercise can help improve the affected limb’s flexibility, strength, and function. Rehabilitating the affected limb also can help to prevent or reverse the secondary brain changes that are associated with chronic pain. Occupational therapy can help the individual learn new ways to work and perform daily tasks.

Psychotherapy.

CRPS and other painful and disabling conditions often are associated with profound psychological symptoms for affected individuals and their families. People with CRPS may develop depression, anxiety, or post-traumatic stress disorder, all of which heighten the perception of pain and make rehabilitation efforts more difficult. Treating these secondary conditions is important for helping people cope and recover from CRPS.

Medications.

Several different classes of medication have been reported to be effective for CRPS, particularly when used early in the course of the disease. However, no drug is approved by the U.S. Food and Drug Administration specifically for CRPS, and no single drug or combination of drugs is guaranteed to be effective in every person. Drugs to treat CRPS include:

bisphosphonates, such as high dose alendronate or intravenous pamidronate

non-steroidal anti-inflammatory drugs to treat moderate pain, including over-the-counter aspirin, ibuprofen, and naproxen

corticosteroids that treat inflammation/swelling and edema, such as prednisolone and methylprednisolone (used mostly in the early stages of CRPS)

drugs initially developed to treat seizures or depression but now shown to be effective for neuropathic pain, such as gabapentin, pregabalin, amitriptyline, nortriptyline, and duloxetine

botulinum toxin injections

opioids such as oxycodone, morphine, hydrocodone, and fentanyl. These drugs must be prescribed and monitored under close supervision of a physician, as these drugs may be addictive.

N-methyl-D-aspartate (NMDA) receptor antagonists such as dextromethorphan and ketamine, and

topical local anesthetic creams and patches such as lidocaine.

All drugs or combination of drugs can have various side effects such as drowsiness, dizziness, increased heartbeat, and impaired memory. Inform a healthcare professional of any changes once drug therapy begins.

Sympathetic nerve block.

Some individuals report temporary pain relief from sympathetic nerve blocks, but there is no published evidence of long-term benefit. Sympathetic blocks involve injecting an anesthetic next to the spine to directly block the activity of sympathetic nerves and improve blood flow.

Surgical sympathectomy.

The use of this operation that destroys some of the nerves is controversial. Some experts think it is unwarranted and makes CRPS worse, whereas others report a favorable outcome. Sympathectomy should be used only in individuals whose pain is dramatically relieved (although temporarily) by sympathetic nerve blocks.

Spinal cord stimulation

Placing stimulating electrodes through a needle into the spine near the spinal cord provides a tingling sensation in the painful area. Electrodes may be placed temporarily for a few days in order to assess whether stimulation is likely to be helpful. Minor surgery is required to implant all the parts of the stimulator, battery, and electrodes under the skin on the torso. Once implanted, the stimulator can be turned on and off, and adjusted using an external controller. Approximately 25 percent of individuals develop equipment problems that may require additional surgeries.

Other types of neural stimulation

Neurostimulation can be delivered at other locations along the pain pathway, not only at the spinal cord. These include near injured nerves (peripheral nerve stimulators), outside the membranes of the brain (motor cortex stimulation with dural electrodes), and within the parts of the brain that control pain (deep brain stimulation). A recent option involves the use of magnetic currents applied externally to the brain (known as repetitive Transcranial Magnetic Stimulation, or rTMS). A similar method that uses transcranial direct electrical stimulation is also being investigated. These stimulation methods have the advantage of being non-invasive, with the disadvantage that repeated treatment sessions are needed.

Intrathecal drug pumps.

These devices pump pain-relieving medications directly into the fluid that bathes the spinal cord, typically opioids, local anesthetic agents, clonidine, and baclofen. The advantage is that pain-signaling targets in the spinal cord can be reached using doses far lower than those required for oral administration, which decreases side effects and increases drug effectiveness. There are no studies that show benefit specifically for CRPS.

Emerging treatments for CRPS include:

Intravenous immunoglobulin (IVIG).

Researchers in Great Britain report low-dose IVIG reduced pain intensity in a small trial of 13 patients with CRPS for 6 to 30 months who did not respond well to other treatments. Those who received IVIG had a greater decrease in pain scores than those receiving saline during the following 14 days after infusion.

Ketamine.

Investigators are using low doses of ketamine—a strong anesthetic—given intravenously for several days to either reduce substantially or eliminate the chronic pain of CRPS. In certain clinical settings, ketamine has been shown to be useful in treating pain that does not respond well to other treatments.

Graded Motor imagery.

Several studies have demonstrated the benefits of graded motor imagery therapy for CRPS pain. Individuals do mental exercises including identifying left and right painful body parts while looking into a mirror and visualizing moving those painful body parts without actually moving them.

Several alternative therapies have been used to treat other painful conditions. Options include behavior modification, acupuncture, relaxation techniques (such as biofeedback, progressive muscle relaxation, and guided motion therapy), and chiropractic treatment.
