I've worked with quite a few clients with Rheumatoid Arthritis. My first few treatments are shorter than usual (20mins-30mins depending on client's condition) as i don't want to cause a healing crisis. For the pain/inflammation i focus on the adrenal glands, circulation and organs of elimination. If the client is on medication then i usually find the liver and stomach to be sensitive so i do extra work on these. Glucosamine Sulphate is a good supplement for R.A.
Hope this helps!
