so after playing a couple of weeks ago, my wrist and hand started hurting pretty bad, so i stopped using it for about a week, within that time, it also became numb-ish at times. well it pretty much went back to normal. but a couple of days ago my wrist started feeling tight. no real pain, no loss of motion or grip strength really. but this tight sensation keeps happening. like there's pressure on it or something. I stopped using it again, but I don't have the money to see a doctor. does anyone know what i can do? and how do the top players prevent injury?
