Sorry to hear about how your feeling. Although I do not have RSD myself my husband had it first in his leg (1995) and now it is in his arm due to a ulnar nerve transposition.

With his leg we found that hot-tub therapy really worked - It sounds like something tho that would not be good for you if the hot water is bothering you.

How about those blocks? I saw RSD_Angel mentioned them too - That would and should be a start for you. Ask your Dr about them and if you do not feel your Dr is taking care of you the way he/she should immediately seek another. You need help right away to insure this does not get any worse on you.

You'll be in our thoughts and prayers. Keep us posted.
