I have had RSD since 2008 it started in my right foot and has now spread to 70% of my body. I have recently started experiencing bad cramps in my legs; mostly at night. The first one hit me so hard I was unable to walk. The cramp was in my right calf, but my entire leg from the big toe to the hip was numb with severe pain shooting up and down. It took a long time for it to go away my husband didn't know what to do. It finally subsided, but my leg was sore for days. I am now experiencing cramps just by moving my legs a certain way; I have to be really careful how I move them. My question is rather anyone else has experienced severe cramps with RSD. I know about he muscle spasms I have them regularly; this is something new and awful. Thanks in advance!
