When I was doing my exercises in the gym, it seems that I somehow strained my triceps. I was doing narrow-pushups at the time when the sharp pain run through my arm and I couldn't push it anymore. Ahhh, it aches when I bend my arm.
It isn't causing inflammation so I don't need to ice the part though I must rest until pain will subside. To a exercising freak like me, it will be a torture staying home for a long time.
