Ulnar neuropathy

Ulnar neuropathy is a condition where the ulnar nerve — which runs along the inner side of the elbow (the “funny bone”) into the hand — becomes compressed or irritated.

Patients typically describe numbness, tingling or burning sensations in the ring and little fingers, sometimes accompanied by weakness in grip strength. The most common site of entrapment is the cubital tunnel at the elbow.

On a cellular level, prolonged compression can lead to nerve fiber demyelination and axonal injury, which amplify neuropathic pain. Early recognition is important, since ongoing nerve irritation can cause long-term deficits. Ulnar neuropathy highlights how localized nerve dysfunction can produce widespread discomfort, illustrating the delicate balance of peripheral nerve health in pain syndromes.
