reflex sympathetic dystrophy syndrome
"Have been taking Savella for 3.5 months - started because of chemo induced neuropathy.  The only side effect that I did not know was a side effect until I read this board, was sweating in head area.  I was having severe pain in both hands and arms and it is virtually gone.  Also, I have lost 13 lbs. and could not figure out what why - guess this could be the miracle for weight loss.  Very pleased with Savella, wish I had known about it two years ago."
