Wrist injury about a year old?

I hurt my wrist about a year ago snowboarding. The pain wasn't bad enough that i felt it was necessary to see a doctor and it doesn't hurt everyday. I feel it when im doing push ups, Curling weights or when im turning something that's requires alot of strength. Could i have developed carpal tunnel or arthritis? To top it off I want to go into the military also, Im afraid if im diagnosed with something im going to be screwed. Maybe im just being paranoid
