i was working out thurday and did biceps and triceps. completely burned out the biceps, so I went back to the barrcks. they had the usual tightness, so I paid no attention to them. later that evening, my platoon sergeant and I got into a groundfighting scuffle (not animosity, just for fun)I think I hyperextended it then, cause when I woke up friday morning, I could fully extend my arm but it hurt pretty bad. so I put icy hot on it to no avail. what would help? stretching it or letting it be? I knowit’s not torn or anything because I can still use it fine, it’s just really tight. any suggestions?
