I have been diagnosed with Hashimoto's. My thyroid levels (T4) are within the normal range even though it went from 0.95 last Nov. to 0.82 this March. I have had severe muscle tightness in my neck and shoulders for the past couple of years and it is only getting worse. I have read about muscle cramps being one of the symptoms and was wondering I am the only person out there that is experiancing this. The muscle on the top of my right shoulder feels like a rock and spasms all the time. Please tell me what I can do for this. My Dr. thinks I'm up in the night and has not put me on any meds for thyroid because the levels are still normal.
