Hi - I am a 48 yr old female with high blood pressure and fibromylgia but otherwise healthy. About 2 years ago, one day out of the blue I was typing on my computer when my last 2 fingers on my left hand suddenly didn't seem to be working fluidly, but awkwardly. Very strange. Now it comes and goes...No rhyme or reason. I feel a little tingling and maybe a little weakness in the forearm. Any clues/
