I am a male, aged 37. I've recently been experiencing elbow pain akind to tennis elbow. I changed the way I slept and typed on the computer, ibuprofen, hot/cold pads etc. Nothing was working. I could barely lift or use my right arm, I was about to make a doctors appointment when the pain started to disappear on its own. I assume through light exercise through a new job. There is now only a slight twinge when I use my arm or sometimes a sharp pain on the inside of my forearm. I've noticed that the swelling has not gone down at all. Along with that I've noticed that two veins are now visible. They travel around the inflamed area and are dark in color though do not protrude. Besides Tennis elbow, what other possible problems could this be?
