I have had a pain on the outside of my elbow for a week now, it hurts to bend it and its now swollen/lump! any ideas??

Bursitis: This could be a bursitis. It may respond to rest, nsaid medications, and elevation.

Pain outside elbow: May be lateral epicondylitis or tennis elbow. You may also have a bursitis if it is a malleable lump. You can try motrin like products if not allergic , an elbow band avoid strenous activities as it comes from repetitive strenous motion. f/u w/ doc http://orthoinfo.aaos.org/topic.cfm?topic=a00068
