Thank you for your answer. Unfortunately, it's not that easy. My blood sugar and b12 are normal, emg did not show carpal tunnel, in fact it did not show anything abnormal. But I am still worried as my right hand problems are getting harder to handle. I can't use it which is difficult, as thumb goes into spasm as soon as I touch it. Usually those are some kind of repeated spasms that move thumb, but sometimes, they look like twitches, I am not sure how to differ those.My wrist is somewhat sore also, so are most of hand muscles, probably of improper use.
I could try with epsom salts, but I am worried what this is.
I used to draw and paint now I can't even hold the pencil anymore of spasms.
