I am going to have outpatient surgery on my left elbow tomorrow morning. A little over a month ago, I came home from work and everything was fine. Then in about an hour my elbow was swelling up for no apparent reason. It hurt like crazy. I scheduled a doctor visit the following week and went to have it looked at. The doctor sent me to an orthopedic doctor who tried to find out what was wrong in his office to no avail. He cut it open with a small incision and could not get anything out. It seems that there is a foreign object inside of my elbow. Right now the swelling is gone but there is a knot that you can move around under the skin. I am curious to find out what I got into to cause this. I do not remember getting hurt, poked, jabbed, stuck or anything that could have caused this. Wish me luck.
