My 44 Y/o Fiance Is A Roofer. He Has Been

My 44 y/o fiance is a roofer. He has been having pain & discomfort in his right elbow. There is slight edema to the outer elbow area. It isnt painful at all times, or even only after working all day, it can be first thing in the morning as well. He has not hit, bumped or had any trauma to the area. What can we try to relieve the pain & inflammation without going to a doctor as we do not have health insurance??
