For a week I have been noticing that the small muscles of my right hand are twitching more and more. Interossei ones, the ones on the top of your hand. That causes my fingers to move, often middle finger, but also the ring finger. On the top of it, I feel something like stiffnes and occassional crampy feeling there..and I feel I can't take it anymore. I'm trying not to think that with these muscles often MND begins but its so frequent now. Just one hand, which is also worse. I rarely twitched on my hands before and now boom, muscles innervated by ulnar nerve are all twitching..the finger movement is terrible to feel, also I feel more shaky.I am sorry for this post, I have been having tought time lately..
