I have this problem that can get worse depending on the day and how I feel, I twitch in bed. I've woken up with pains in either my groin, leg, arm, shoulder, hand, etc since I was a kid. never knew why. Recently I've noticed I lightly wake up and I could be twitching. When I mentioned it to my mom she said she remembered seeing me twitch in my sleep. I think that's why I wake up in pain, it's worse on days like my period or something important like an interview or a test. Anyone else have this problem?
