Cubital tunnel syndrome is a condition that occurs when the ulnar nerve becomes compressed or irritated at the elbow, leading to symptoms such as numbness, tingling, and weakness in the ring and little fingers. Treatment options include avoiding activities that exacerbate symptoms, using a splint at night to keep the elbow in a straight position, and performing exercises to strengthen the muscles around the elbow. In some cases, surgery may be necessary to relieve pressure on the ulnar nerve. Seeking medical advice is important to prevent long-term nerve damage and improve symptoms.
