Thought I'd see if anyone else has had this issue and what the fix was. I have been mtbing for about 5 months now. About 6 weeks ago, I began to notice pain in my left hand where the fingers and hand meet. It wasn't bad, just annoying. It has gotten progressively worse, and during a race yesterday I actually had to stop to let the pain subside. It tends to happen most when I am modulating with the front brake. I have had a few crashes the past coupel months, and during one crash I messed up my left thumb pretty bad but I can't recall any specific hand issues. The pain feels a lot like a strain of some sort.... strong burning sensation.
I have been fitted to the bike and like I said the pain is somewhat new. No issues with the right hand at all. My grips are Oury if that matters. I circled the area where the pain is. Planning to schedule an appointment with a doc as well to get it checked out.
