Wierd feeling in my side. What is it?

I always get a sharp stabbing feeling on my right side. Then from my pinky all the way up to my elbow feels funny, and I can't feel hot or cold. Makes me wonder if I just have weird nerves or something. The breathing like this sucks. XP So I hold my breath and slowly exhale so it doesn't hurt so badly. I get it at least twice every two weeks.
