Dubious mentioned warm bath and then a walk, I have found that gentle exercise helps greatly. After a suggestion from my orthopedic surgeon (who first suspected I had CRPS) I have been doing water therapy. For basically the same as the $20 per visit insurance co-pay, I go to the YMCA and do their water rehabilitation. I have a rehab specialist who has gone to training to do water rehab. She works for the YMCA after approaching her wish my diagnosis she did research as to what would be best for me. She is very knowledgeable on gentle exercises, you get the great weight bearing exercise in a 85 deg pool. I highly recommend it especially if you miss a lot of physical movement/exercise. Hope this helps!! Best wishes for a pain free day!
