Hi, I'm really not sure where to post my question. I had back surgery in 2003. Microdissection of L3-5. It stopped the numbness in my left leg, but I was left with much pain. I also have anxiety/panic disorder. For the last year or so, just now and then, I get twitching in my muscles. My legs, arms, shoulders, everywhere. Only after I start to relax while going to sleep. A soon as I start to fall asleep, something twitches. Almost like a tiny convultion.
