I had surgery on right hand about 10 years ago and the difference was amazing. I had the study on on left hand about a month ago, and confirmed that I have it there too. Was a waitress for 30 years, that's where mine came from. When symtoms first started I thought I was going to have a heart attack. Wear brace at night, if I don't I wake up in severe pain. Numbness almost all the time, but don't want surgery again. Yuck!!!
Try doing the brace, it may help.
