My nerves seem to be going crazy too. My right middle finger twitches sometimes then it takes several days off from twitching. Then my left arm (on the in side near my eldow) begain to twitch also. sometimes I think it's from playing the basss guitar because a play so hard I get blood blisters on my right index and my twicthing finger quite often. I get restless and some anxiety at night.
I just realized that my middle finger twitches when I played the bass guitar intensely or after I did some tough garden work using my right hand.
I don't know what's going on with the rest of my body though. Between my elbow and wrists feels like it's burning some times now.
I have an appointment to see a neurologist Aug. 10. Sometimes I have a hard time waiting for that appointment.
