You can get tennis elbow by overusing your forearm. This can be from a repetitive or strenuous activity.
It can sometimes happen after banging or knocking your elbow.
If you strain the muscles in your forearm, tiny tears can develop near the bony lump on the outside of your elbow. This lump is the lateral epicondyle. It can then get inflamed.
