I'm concerned with something in my elbow. My right elbow extends all the way, no problem. The left one however, is not able to reach the full limit of its flexion. It doesn't feel any different than the right, it just doesn't extend the full way. Id say it probably gets about 90%. The reason I'm concerned is I plan on enlisting in the Army Option 40 (ranger) and you have to score a 11111 on the PULHES system. I'm not sure what the standard is for joint flexibility, but I'm worried because I've read that it can cause elbow joint instability and the likes. Any insight?
