So, I competed in NAGA southwest championships this past weekend in Fort Worth, TX. I had a complete adrenaline dump in my first match (won 6-0) and only had one match in between my next match to rest (about 5-6mins). That guy had a by and was fresh. I was so shot i could not lift my arms for 2nd match. I take the guy down into a guillotine choke but with no strength in my arms he eventually gets out. I didn't even have the ability to wrap him up in guard or bring my other arm over to grab my arm under his neck. He gets side control and attacks my left arm with key lock. He is cranking it but not super fast or anything. Now my shoulders are the most flexible part of my body and keylocks/americana's rarely work on me before the person gives up the submission attempt. I feel no pain at all and then all of a sudden my elbow pops, he immediately stops and looks at the Ref like "his elbow popped" I replied "dude it didn't hurt it is fine." He commences to go further and I basically told the guy, I have no energy I will tap for you and I did. He said he was about to let it go because he was so far back and it wasn't affecting me. Maybe the way he twisted my elbow it made it pop but I felt fine afterwards and my arm had complete range of motion. I have a small bruise on the medial side of my elbow and it is tender but no swelling. Sunday I started to suspect that I may have torn my UCL (ulnar collateral ligament) the one baseball players tear when they need tommy john surgery and are out for 1 1/2 years. Went to doctor and he said to take 8 weeks off and that he doesn't feel any instability in the elbow but that my symptoms are consistent with a UCL tear. I am getting an MRI for peace of mind for me just to see if it is maybe sprained (torn a little or more than that). Either way i do not want this injury. I still have all my strength and this is my non throwing arm. Don't know what to do.
