No Way! Knitting Injuries

I just can't believe this. I have knitted so much lately that I have a knitting injury.

Have you ever gotten a knitting injury? My left thumb hurts. I must have poked it one to many times. I use wooden knitting needles. The skin is peeling off on the cushy part and there is a sore at the joint. I have neosporin on it now with a band-aid on it. I still want to knit so I either would have to take a break or I wrap up my thumb so I can knit. Any suggestions/opinions?
