I hyperextended my elbow last night rolling, i got caught in an armbar, and I didn't tap for maybe 20-30 seconds (I didn't feel anything), until all of a sudden I felt an extremely sharp pain and it just bent the other way. I kept on going another maybe hour, hour and a half without any pain. I got home and I had no pain whatsoever. I then woke up around 3 a.m. not being able to straighten my elbow and pretty bad pain, I was just wondering what I could do for it to heal, without going to a doctor?
