You sound like me seven years ago. My hand was huge with swelling and the fatigue and weakness were such that I had to use a cane to stand. I had weird symptoms like pain behind my ears! I was diagnosed with psoriatic arthritis, which I now believe was accurate. I made the difficult decision not to take methotrexate or immunity lowering drugs because they told me I would have to be on them for life or my problems would come back worse than ever. So I decided to work on my diet instead. It took about 9 months to start working though, and during that time I did get somewhat severe joint damage in the hand that was swollen. Since then the only symptom I've had is a little itchy scalp once in awhile, usually after the holidays when I've let myself go off my dietary guidelines. About that, broadly speaking, I'll only say that most of what I eat falls loosely into the category of anti-inflammatory. I'm not trying to promote any specific therapies. I just wanted to share my experience to add to the information offered here.
