The peripheral nerves of the body come together as a part of an extensive and complicated network. These nerves allow the spinal cord and the brain to communicate with all areas of the body. However, these nerves can also easily become damaged because they are fragile.
Peripheral nerve injury could be minor, or it could result in a completely severed nerve. Regeneration of the nerve might be possible, but that will be determined by the amount of damage, as well as the type of damage, that was caused.
A peripheral nerve could become compressed or entrapped as a result of several conditions, including carpal tunnel syndrome, ulnar nerve entrapment, and anterior interosseous neuropathy, as a few examples.
Hypothyroidism, rheumatoid arthritis, polymyalgia rheumatic, gout, carcinomatosis, acromegaly, diabetes, and amyloidosis are some of the conditions that could increase the risk of peripheral nerve injuries.
Common causes for nerve injuries include surgery, injections, stretch, compression, electric shocks, laceration and contusion.
These injuries are classified into five different degrees according to severity. A first-degree injury might be easily reversible while a fifth-degree nerve injury requires reconstructive surgery.
The symptoms most commonly caused by peripheral nerve injuries include pain, numbness, and a burning sensation in the area that has been affected. Additionally, a person can also experience tingling, muscular weakness, pricking and sometimes develop an exaggerated sensitivity to stimuli such as an intense sense of touch.
When a peripheral nerve is injured, the only treatment may be surgery. This may also be necessary if there are neurologic symptoms that are persistent, and if conservative approaches have not worked.
Peripheral nerve problems can be treated in order to eliminate, or at least reduce, symptoms. Non-surgical options include physical therapy, immobilization, and medications.
