After decades of lifting, a few years ago I developed a hematoma in my left elbow. One culprit that led to it was tricep pressdowns. So, I backed off of doing them, benching, and militaries. That's what you have to do to get over those type of injuries; there's no way around that. My size and strength suffered, but the last thing I want is to end up crippled. So, I'd suggest reducing the intensity of your workouts and following some of the advice provided above. Experiment. Find out what you can do to achieve the same or similar effect without endangering the bodypart in question.
