Hi guys:I haven't dropped a worried post in several weeks now. I had a normal MRI a few weeks ago and have generally had pretty stable symptoms since. I hadn't even worried about ALS in weeks and weeks.My left hand, which had never really bothered me too much, has been acting up today. I've had a weird feeling in the muscle in the webbed area between my thumb and index finger for several weeks. It's kind of a like a twitch, but not exactly like the others I get. It almost feels like I'm getting a mild electric shock or something is crawling around in my hand. Tonight, the feeling is there, but it's stronger. I'm also getting some other weird sensory symptoms in that area - kind of like tingling but not exactly. I'm also worried that the muscle there looks a little atrophied. I know it's a little smaller than that of the other side, however I can't swear that it hasn't always been - it's not my dominant hand, and since I hadn't really had problems with it before I never really "examined" it. I'm not sure why I'm getting concerned, and I know people here have had similar symptoms and concerns. I know the tingling, weird sensations have been experienced by others. Anyone else notice that this muscle on their non-dominant hand is noticeably smaller? (Sorry if this is a stupid question - I'm in reassurance-seeking mode again and I hate it.)Joanne
