Actually my right hand is way worse than the left, but the left just started acting up. Pooh. I had a really bad reaction to a bier block so I don't think they'll try them again. I would lobe to just get it got the right. I typed in six classes of grades and I do it ten key style. Kills my wrist yikes! I have an appointment Wednesday. I hope to get the ball rolling again. Never thought I'd consider it, but the leg one is awesome so might as well at least do the trial. How do you keep your neck still? Where is the lead or leads? Where is the battery pack?
