Have they checked your Vitamin D levels? I am on a whopping big dose of vitamin D right now for 12 weeks for different kinds of arthritis.

-. Eat really nutritious foods. Lots of protein because it heals the body! nuts, meat, fish, eggs, chicken, etc.
- drink lots of green tea with honey and lemon
-Then fast 3 days. It kicks in healing.
- take relaxing ginger baths
-Get lots of sunshine, vitamin D, and take multivitamins omega 3
