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 ...
The experience of nerve pain is described with a variety of terms: burning, hot poker, itching, tingling, lightening, shooting, electrical, and so on. In medical terms, words like hyperalgesia and allodynia are used. Hyperalgesia means that an area is overly sensitive to painful (noxious) stimuli like a pinprick. Allodynia means that an area is overly sensitive to normally non-painful (non-noxious) stimuli like light touch. Both of these phenomena are hallmarks for nerve pain.
Many common ailments cause nerve pain. The most recognizable cause of nerve pain is diabetic peripheral neuropathy. The nerve damage caused by abnormal blood sugar levels cause the nerve to dieback in a "stocking and glove" distribution. First, the area of the foot and ankle region (stocking area) is usually affected with numbness and tingling. As the neuropathy progresses, burning pain will begin as well. Diabetic peripheral neuropathy is a classic example of nerve pain that is generated in the peripher...
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...
