My age is 46 years. I am a male. I am suffering from a problem in my left thumb. I am not able to lift or move my thumb by my own. It seems like I have lost my control on my thumb. My voluntary muscles are not responding in the left thumb region. Please suggest any remedy. Please help urgently. I also had a problem of this kind only in my right index finger and middle finger. But the problem vanished after few months. Now this had appeared in my left thumb. Please help.
