For others: GCA is giant cell arteritis (I looked it up). I am not clear on what the 3/4mg alternating refers to.

I have burning, pain and stiffness all over, which started suddenly (I was okay at 6am but full flare at 8am) so was interested in your post. Long history of "paresthesias" and "neuropathy."

Sorry not to be helpful. In my experience doctors don't really understand these sensations and experiences.

Blood testing and biopsy helped with my diagnosis of lupus (which I find questionable) and I have a very high antibody for limited scleroderma. I am afraid I just don't expect answers anymore and get what I can from doctors in the meantime. I am sorry you feel your doc doesn't understand!
