What is the first treatment for cubital tunnel syndrome?

Cubital tunnel syndrome involves irritation or compression of the ulnar nerve as it passes behind the inner elbow. Keeping the elbow bent for long periods can narrow the space around the nerve and trigger tingling in the ring and little fingers, aching at the elbow, or hand weakness. A clinician may recommend avoiding direct pressure, changing work or sleep positions, and using a light splint to limit prolonged bending. Learn more about [Cubital Tunnel Syndrome](/conditions/cubital-tunnel-syndrome/).

Avoid leaning on the elbow and take breaks from activities that keep it bent. At night, keep the elbow in a comfortable, more open position; [Splinting](/treatments/trauma-and-fracture-care/splinting/) may help when a clinician advises it. Gentle movement is usually preferable to forcing stretches or exercises that reproduce numbness. A physiotherapist can assess posture, nerve irritation and hand function through [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/).

Arrange medical assessment if numbness persists, symptoms disturb sleep, grip becomes weaker, or the small muscles of the hand appear thinner. Seek prompt care after a significant injury or when the hand becomes cold, pale or severely painful. If non-surgical measures do not control symptoms or nerve weakness is progressing, a specialist may discuss [Cubital Tunnel Release](/treatments/reconstructive-orthopedic-surgery/cubital-tunnel-release/).

Which positions or tasks are irritating my ulnar nerve? Should I use a night splint, and how should it fit? Do my grip and finger muscles need testing? What change would mean that treatment needs to be escalated?
