This can lead to cerebral edema, potentially resulting in seizures, permanent brain damage, or death. Therefore, significant hypernatremia should be treated carefully by a physician or other medical professional with experience in treatment of electrolyte imbalance .
Peripheral edema is edema (accumulation of fluid causing swelling) in tissues perfused by the peripheral vascular system, usually in the lower limbs. In the most dependent parts of the body (those hanging distally ), it may be called dependent edema.
These injuries will lead to edema and fibrosis, not just in the nerve but also the surrounding tissues touching the nerve, which may further inhibit normal nerve gliding in a vicious cycle. [ 2 ] The most commonly understood mechanism of impaired nerve gliding is through the formation of scar tissue that adheres separate tissue planes.
Edema may be described as pitting edema or non-pitting edema. [32] Pitting edema is when, after pressure is applied to a small area, the indentation persists after the release of the pressure. Peripheral pitting edema, as shown in the illustration, is the more common type, resulting from water retention.

Entrapment and compressive neuropathy syndromes occur due to compression and/or constriction on a specific location for a segment of a single nerve or multiple nerve sites. This entrapment or compression can be diagnosed based on multiple factors including physical examination, electrodiagnostic test and clinical history.
A pinched nerve occurs when pressure is placed on a nerve, usually from swelling due to an injury, or pregnancy and can result in pain, weakness, numbness or paralysis, an example being CTS. Symptoms can be felt in areas far from the actual site of damage, a phenomenon called referred pain .
