Teres minor. Source of symptoms resembling ulnar neuropathy or C8 radiculopathy

Numbness and tingling in the ring and little fingers (fourth and fifth digits) is usually associated with a radiculopathy (C8) or compromise of a peripheral nerve (ulnar). The presence of a trigger point in the teres minor muscle may produce similar symptoms. Early diagnosis and appropriate treatment will save the patient unnecessary discomfort and reduce the use of sophisticated diagnostic testing.
