What to do if i am wondering how you can tell the difference between a bursitis at the elbow and tendonitis at the elbow?

The location: The bursa or fluid filled sac is located over the olecronon process. This is the tip of the elbow which many people lean on. Because of trauma it often gets inflamed. Tendinitis typically occurs on either side of the elbow, close to where the wrist flexor tendons (medial epicondylitis) or wrist extensor tendons (lateral epicondylitis) attach to the bone.
