Well! : As long as u have full pom & it is painless u may have olecronon bursitis. This would present as a fluid filled sack @ the tip of the elbow. U should b cn by an orthopedic surgeon 4 eval, xam & x- rays 2 b sure. If this is what u have some may aspirate & inject with steroids. If there's any abrasion or cut over the area there is a chance of infection. Increase in pain swelling & pain report right.
