I'm just casting a broad net here. My sister has been experiencing chronic, daily, excruciating pain in pretty much all of her joints. She's young (just turned 30) and in good health otherwise. It's been many months now and she is really suffering. She's been to a lot of doctors (GP, Neurologist, Endocrinologist, Rheumatologist etc) and undergone a lot of tests, but so far they've turned up nothing. She's been tested for Lyme's, MS, and a bunch of others that escape me at the moment. Has anyone else experienced anything like this?? I feel so helpless for her. She's got another round of doctor's appointments today...more tests. She's hoping they'll order an MRI. She's worried she's going to wind up with the DX of Fibromyalgia...the catchall. The only other thing I was able to suggest to her was seeing an Allergist and that maybe she was allergic to something (wheat? gluten??).
