I've been searching and searching the internet for answers. I was recently diagnosed with very early Thyroid Cancer (Only 1 cm in 1 nodule). I thought this was the answer to some of the symptoms I have been feeling over the last 6 months or so. I am told that it's not. That the cancer is to small for me to have had ANY symptoms at all. So now I'm baffled and still looking for answers. Here are my issues: I have had shoulder pain, neck pain and mid back pain (Center of back and up). It's not extremely painful but it's a weird feeling. I would say sometimes cold and prickly and sore. I'm thinking some sort of neuropathy. I have had this for months now and can't get any relief. I also am extremely tired, no libido, freezing all the time, dry skin, irregular periods (but I'm close to menopause). So now that I have found out that I have Thyroid Cancer, could it be throwing my Thyroid off and causing these symptoms? Once it's removed, and I'm balanced out on meds, should I feel better? I'm mainly concerned with the muscle pains/aches. Just curious if anyone else had back pain as a symptom. Thank you so much!
