Has anyone ever had any experience with someone with CAH also suffering with RSD (reflex sympathetic dystrophy)?  My daughter had pretty routine arthroscopic knee surgery May 9.  By the beginning June her pain was escalating instead of going away.  She is now in constant pain.  We have been doing physical therapy since June 2-3 days a week at a local PT center, we exercise her leg and stretch it every night at home, she has been taking medication to try to calm the nerves and it keeps getting worse.  I read somewhere that stress can affect this condition.  Well, I wonder if the CAH plays a part in this.  Right now we are scheduled for her to get a lumbar sympathetic nerve block next week to relieve her chronic severe pain.  Any advise/experience you could share would be greatly appreciated
