Neuropathy - distal median nerve
Pain in the wrist or hand that wakes you up at night
May be severe Pain may be felt in other areas, for example in the upper arm (this is called referred pain)
Sensation changes in the thumb and pointer (index), middle, and part of the ring fingers, such as:
Weakness of the hand that causes you to:
Drop things Have difficulty grasping objects
Signs and tests
Your doctor will examine your wrist and ask questions about your medical history. The examination may show decreased sensation in the thumb side of the hand. This is called the "radial" side. There may be weakness of the thumb and difficulty using it to pinch.
Tests that reveal distal median nerve dysfunction may include:
Nerve conduction tests
Tests are ...
Definition Tibial nerve dysfunction is a loss of movement or sensation in the lower leg, caused by damage to the tibial nerve. Alternative Names Neuropathy - tibial nerve Causes, incidence, and risk factors Tibial nerve dysfunction is a form of peripheral neuropathy . It occurs when there is damage to the tibial nerve, one of the branches of the sciatic nerve of the leg. The tibial nerve supplies movement and sensation to the calf and foot muscles. Dysfunction of a single nerve group, such as the tibial nerve, is called mononeuropathy . Mononeuropathy implies a local cause of the nerve damage, although occasionally systemic disorders may cause isolated nerve damage (such as occurs with mononeuritis multiplex ). The usual causes are direct trauma, prolonged pressure on the nerve, and compression of the nerve from nearby body structures. Entrapment involves pressure on the nerve where it passes through a narrow structure. The damage may include destruction of the myelin sheath of the nerve (the in...
Definition Ulnar nerve dysfunction is a problem with the ulnar nerve, which travels from the shoulder to the hand and allows movement or sensation in the wrist or hand. Alternative Names Neuropathy - ulnar nerve; Ulnar nerve palsy Causes, incidence, and risk factors Damage to one nerve group, such as the ulnar nerve, is called a mononeuropathy. Mononeuropathy means there is nerve damage to a single nerve. Both local and body-wide disorders may damage just one nerve. The usual causes of mononeuropathy are: An illness in the whole body that damages a single nerve Direct injury to the nerve Long-term pressure on the nerve Pressure on the nerve caused by swelling or injury of nearby body structures Ulnar neuropathy occurs when there is damage to the ulnar nerve, which travels down the arm. The ulnar nerve is near the surface of the body where it crosses the elbow. The damage destroys the nerve covering ( myelin sheath) or part of the nerve (axon). This damage slows or prevents nerve signaling. Damage ...
