Look for a "Tennis Elbow" brace. They fit, and apply pressue just below the elbow. Wear them all the time until things get better.
Years ago, no, maybe a couple of decades ago I had tennis elbow and golfers elbow on my right arm (I'm right handed) from working on the bottom of my boat (36' sailboat needs new bottom paint every 3-4 years), sanding, scraping. I wore a tennis elbow, and a golfers elbow brace for several weeks. I was still working at the time.
