Hi, I'm concerned I may have carpal tunnel syndrome. I was helping my grandpa move some 40Ib bags of wood pellets for a heater, and a few hours hours afterwards, I tried popping my fingers on my left hand and my wrist hurt real sharply. I've also had this red spot on my left wrist for a day or two, and I think I may have bled under my skin, this was before helping my grandpa, so I'm not sure what caused that.
