When it comes to chewing gum, it's the type of gum you chew that makes a difference in whether it's helpful or harmful to your teeth.

The olecranon process is the prominent bony projection of the ulna bone that can be felt at the elbow. Hook-like in shape, it is the structure that curves around the bottom of the humerus bone in the upper arm and encapsulates the elbow joint. It also is the site of attachment for several muscles of the arm.
Olecranon bursitis causes pain and swelling in the area at the tip of the elbow. It may be very difficult to put the elbow down on a surface due to the tenderness. If the condition has been present for some time, small lumps may be felt underneath the skin over the olecranon.
