![]() Tenderness in the elbow joint at the “funny” bone. Activities that use the arm may increase the pain. Pain (which can manifest itself as a burning sensation) in the elbow, palm and/or last two fingers. This may be worse at night while sleeping. Numbness, tingling or decreased sensation in the palm or last two fingers. Hand weakness (especially of the little finger and hand grip). ![]() Symptoms of ulnar nerve damage (neuropathy) may include: As the syndrome progresses, it may become more difficult do during certain tasks with the hands. Often symptoms develop gradually and may only include weakness initially. Sex: Women are more likely to develop ulnar tunnel syndrome than men.Īlthough there are many known factors that can contribute to the development of cubital/ulnar tunnel syndrome, there are cases where no cause can be identified. Here, the symptoms typically go away after delivery. Pregnancy: Hormonal changes can lead to fluid retention. Long-term pressure on the base of the palm. Over time, this back and forth movement can irritate the nerve.Ĭonditions that cause long-term swelling or inflammation near the nerve. In some people, the nerve moves back and forth as the elbow is bent and straightened. Medical conditions that can lead to nerve damage (like arthritis and diabetes).Ībnormal growths: Development of a tumor or cyst that presses against the nerve. Prolonged, repetitive use of the arm or elbow (including leaning on the elbow).Įlbow injuries: Any trauma (fractures, dislocations or sprains) can cause swelling or compression. Things that can contribute to the development of cubital/ulnar tunnel syndrome include: What are the Causes of Ulnar Nerve Entrapment? It is the excessive pressure on the nerve causes symptoms. The ulnar nerve is surrounded by a ligament that (under certain conditions) can thicken and compress the nerve. ![]() However, the elbow is the most vulnerable point because the ulnar nerve is near the surface and travels through a small space (called the cubital tunnel) within the elbow. The ulnar nerve can be compressed as it passes through the elbow or wrist. It controls the movement and sensations for parts of the hand (specifically, the fourth and fifth fingers, the palm, and the inside portion of the forearm.) The ulnar nerve travels from the shoulder, down the arm and into the hand. The condition is caused by compression or irritation of the ulnar nerve. It can cause numbness, tingling and/or pain in the arm and certain fingers. It’s the second most common nerve entrapment after carpal tunnel syndrome. Ulnar nerve entrapment is also called cubital tunnel syndrome and ulnar tunnel syndrome.
