![]() Most susceptible are people over 30 who work using overhead motion of the arm. The forearm muscles become weakened and damaged from overuse, putting strain on the tendons. It is caused by using the arm in repetitive motion, such as swinging a tennis racquet. Tennis elbow, or lateral epicondylitis, is an inflammation of the tendons that connect the muscles of the forearm to the side of the elbow. Urgency: Primary care doctor Tennis elbow (lateral epicondylitis) Top Symptoms: hand weakness, weakness in one hand, numbness in one hand, pain in one elbow, pain in one forearm Surgery is usually not needed unless the nerve compression is causing weakness and loss of use in the hand. Treatment begins with wearing a supportive brace and adjusting activities to avoid further irritating the nerve. Symptoms include numbness and tingling of the hand and fingers, sometimes leading to weakness and even muscle wasting in the hand.ĭiagnosis is made through physical examination, x-ray, and nerve conduction studies. ![]() Fluid buildup and swelling inside the elbow previous elbow fracture or dislocation or leaning on the elbow for long periods of time can put pressure on the ulnar nerve inside the cubital tunnel. ![]() The exact cause for entrapment may not be known. Entrapment often happens in the cubital tunnel, which is the narrow passage at the inside of the elbow. This very long nerve can become compressed, or entrapped, by other structures at certain points along the way. The ulnar nerve begins at the spinal cord in the neck and runs down the arm into the hand. Ulnar nerve entrapment of elbow is also called cubital tunnel syndrome. This list does not constitute medical advice and may not accurately represent what you have. Hand weakness ensues when a variety of syndromes - known as neuron syndromes - affect these neurons. Motor control capabilities are dictated by neurons.
