A pinched nerve is the result of mechanical or movement-based compression of a nerve as it interacts most with bones, discs, muscles, but can also get pinched by tendons or ligaments. When the nerve is severely pinched the pressure disrupts the nerve’s function, causing pain, numbness, weakness, or tingling. The most common cause of a pinched nerve is a herniated disc usually involving the sciatic nerve
Most common nerves that are severely pinched:
- Spinal nerves (Lumbar and Cervical Nerves)
- Sciatica nerve (Sciatica)
- Ulnar nerve (Golfers Elbow)
- Median Nerve (Carpal Tunnel)
- Radial Nerve (Tennis Elbow)
When a nerve becomes severely pinched it’s unable to properly regulate its blood flow with the blood coming in becoming blocked like water at a dam by a herniated disc or dynamically pinched by tendons or ligaments. It begins to swell and is compressed by the external pressure (disc) and then the nerve is compressed from within from internal pressures (blood flow). If mild this irritates the nerve, and if the nerve is severely pinched, then it’s damaged.
