Nerve compression is caused by direct pressure on the nerve, known as a trapped nerve. This causes tingling, numbness, and/or a burning sensation around the body affected by its corresponding nerve. These signs and symptoms can occur directly after the insult or injury occurs, which means hours or even days after. Pain is not a common symptom of nerve compression.
The most common nerve compression syndrome is carpal tunnel syndrome.
External pressure reduced the flow of blood to the nerve, causing ischemia which eventually leads to scarring.
Nerve compression can be diagnosed solely based on the symptoms and signs alone. However, nerve conduction studies are helpful in confirmation of the diagnosis. The study can help calculate the severity and rule out an involvement of other nerves.
The underlying medical condition causing such neuropathy, should be treated directly. For example, if weight gain is the direct cause, then, a weight loss program would be appropriate. Some neuropathies such as a carpal tunnel would require surgery to release the entrapped nerve.
