A year ago I developed numbness and tingling in fingers 4/5 L hand, tingling remains, no weakness. Cervical and brachial plexus MRIs negative, xray neg, EMG/NCS neg. Past few months have constant fasciculations, cramping, feelings of caterpillars under my skin lower leg, keeps me up all night. Klonopin .5 q hs helped. Nov 7 developed intermittent though very frequent icy hot burning sensations that sweep over r side of my face lasting approx 30 sec. Brain MRI w/w/o gadollnium neg. Neuro MD says atypical facial pain--gave Neurontin, no relief yet but burning sensation now traveling down r arm to fingers. Is this some sort of preliminary neuro disease or anxiety. I have been under extreme stress for the past two years, and was treated for panic attacks off/on since 85. I am really scared that this might be MS, MD, ALS, Guillain Barre, something or am I just going crazy? As a nurse I know a little about this, just enough to make me become very scared or should I just attribute this to anxiety? The MDS just don't know what to make of it as all tests are negative. Any help would be much appreciated.
