I started suffering a lot with tennis elbow in my bow arm several years ago. I tried shooting less, but it didn't really help. When I shot, it hurt! I was shooting 62#, which was my favorite pull weight for many years.
Finally early this year I dropped down to 45# and it was therapuetic. After a shooting session my elbow felt better and if I didn't shoot every day, it would start to get sore again. After a few months, I moved up to 50#, then up to #55, which is where I am now. Still a tiny amount of discomfort after shooting a while, but very manageable now.
