Yeah, i'm going to do as much cardio etc as i can... think i'm going to go and run some hills today; but i can't even lift weights or anything, or even skip i doubt with this splint imobilizing my thumb... 4 weeks is going to feel like forever... i think i must have caught my thumb when i was chasing in the ring during a punch or something, and dr said the pain can move into the wrist and down the arm...as i said i'm a beginner, but i've been told to punch with my ring and pinky... dr. looked at my left pinky too as its knuckle has been sore for weeks and said nothing bad there nothing broken...probabaly just need to toughen up there... i have no probs with a little pain... i wrap and thats all good. Any words of wisdom... further suggestions?
