Should I be concerned about my treatment for Hashimoto's?

I was diagnosed with Hashimoto's Disease in 1994. For the past 2 1/2 years I've been dealing with various muskuloskeletal problems such as scoliosis, herniated discs, tendonitis, bone pain& osteoarthritis. I've taken muscle relaxants, anti-inflammatories and Vitamin D. I've had Xrays and bone scans. I've tried physical therapy, chiropractic and accupuncture. I started to feel better last summer after the Endocrinologist increased my dosage of Levoxyl from 137 to 150 mcg. Then, after a followup appointment he lowered it again. I mentioned to my rheumatologist that I was feeling better during the summer and my muskuloskeletal problems flared up again after my Levoxyl was reduced. She ordered more blood work and found I had a TSH oh 10.5! I called the Endo, but he doesn't want to do anything until he sees me again in May '08. He thinks the bone/muscle pain I'm experiencing is unrelated to the Hashimoto's. I struggle to find words because I have brain fog. I used to be a runner.
Answers?

i'm so sorry to hear you aren't feeling well! have you thought of finding a new doctor? you shouldn't have to suffer! i hated my endo and will never go back to an endo again. my doc is a allergy/autoimmune specialist he prescribes armour thyroid for me, which is a natural thyroid med. also, i need to up my dose in the fall and winter and decrease it in the summer and fall and i have heard of others that need to do this also.
