Hello, I've got arthritis and have also been living with recurrent hip tendonitis, shoulder bursitis, plantar fasciitis, Achilles tendonitis and hand joint pain. I've been seen by a rheumatologist as I thought they may be connected but the blood tests didn't pick up anything. I have found the tendonitis in my hip so debilitating, I've had two steroid injections in it that helped temporarily and I've also had months of physiotherapy but it's still so painful. I've read sometimes drs treat chronic tendonitis with Radiotherapy and wondered if any one had experienced this type of treatment? Thanks for reading my post.
