Nerve damage refers to any harm or injury caused to a nerve or group of nerves. This can result in a range of symptoms and disabilities, depending on which nerves are affected and how severely they are damaged. Nerve damage can be caused by various factors such as trauma, disease, exposure to toxins, or prolonged pressure on the nerves. The consequences of nerve damage may include pain, numbness, tingling sensations, weakness, loss of sensation, and difficulty controlling muscle movement. In some cases, nerve damage can be permanent, while in others it may heal over time with appropriate treatment and care.
