What is cubital tunnel syndrome caused by being on the computer about 7 hours a day could that cause cubital tunnel syndrome ?

Here : Here is a copy of my answer to another user with the same question: contrary to popular belief, most cases of carpal tunnel syndrome are "idiopathic, " that is, we don't know the cause. Cubital tunnel syndrome is similar. It is compression of the ulnar nerve at the inside of the elbow. Similar to the carpal tunnel, there is a bony base--the medial epicondyle of the humerus--and a ligamentous roof--osborne's ligament. Why nerves get compressed is still a mystery. However, there are certain things to avoid once you have cubital tunnel syndrome. A tightly flexed elbow, such as when talking on a small cell phone or doing hair and make up, stretches the nerve around the bone. Leaning on the elbows can pinch the nerve more and make symptoms worse. At night, avoid sleeping with the elbows bent or resting on the inner elbow. Some people have a known cause, such as an old fracture that causes the medial elbow to be longer and therefore stretch the nerve (cubitus valgus). Some people have ulnar nerves that jump out of the groove (subluxate). Others have had a direct impact that injured the nerve. Most people don't need surgery for cubital tunnel syndrome. It tends to respond well to physical therapy with nerve glides--exercises designed to move the nerve through its tunnel. However, if there is constant numbness or you develop weakness, the nerve may need to be released or moved to a location where it is less likely to be compressed.

Simply Compresion : Simply compresion of the ulnar nerve at the elbow. Why is it compressed? This is the part that can be complex. Abnormal bands of tissue, abnormal variants in mucles at the elbow, repetitive activity, predisposition to having nerve compression due to a systemic issue such as diabetes or thyroid disease. All have been implicated.
