I developed severe tendonitis in my elbow from throwing the javelin in college. I tried everything medically available in the late 60s but was not able to find a cure. After months of therapy and seeing several specialists, I had to give up the javelin throw. Although I have big time problems with my back and knees, swinging a detector has never bothered my elbows. However, even 50 years later my elbow does hurt when I just think of throwing a javelin.
