Diet changes for me. My joint pain was a symptom of autoimmune issues, but eliminating certain things from my diet has helped immensely. I went gluten free first, at the advice of a friend, and my overall joint pain (hands, wrists, shoulders, hips, knees) was gone 48 hours later. Still had some minor swelling in fingers/wrists but that was gone within a week. Always the skeptic, I thought maybe it could just be a coincidence… but then about a month into being gluten free I accidentally ate something with gluten and had joint pain the next two days after, then gone again.
My Rheumatologist also recommended eliminating most foods in the night shade family (white potatoes, eggplant, tomatoes, peppers, tomatillos, and goji berries), corn, white rice, and dairy as all of these are inflammatory. We compromised a bit as I was not willing to give up everything at once, so I do not eat gluten, corn, potatoes, white rice, etc. but do allow myself limited non-fat dairy (cheese & yogurt mostly) and tomatoes/peppers occasionally. And I did cheat a few weeks ago and had some home made popcorn without issue…
I told a friend about my experience a few months ago and she decided to cut out gluten and dairy, as she suffers from terrible lower back pain due to an injury. She called me about 2-3 weeks in and said that she was about 90% pain free! She also added a home made turmeric tea, but I have not tried that yet.
Anyway, might be worth evaluating your diet in addition to some of the other suggestions.
