I have had this pain in my left palm off and on for a couple months. It doesn't hurt to ride, just to lift things or stretch my fingers out. It hurts the worst when I lift weights...like doing a bicep curl - it feels like the tendon is ripping out of my hand. It is visibly swollen and tingles a lot. Anyone had carpal tunnel or know about it? I thought that was in your forearm and wrists?
