Common causes of pinched nerves include disk protrusions into the neuro foramina and bone spurs. Less often, scar tissue that has formed from a previous surgery can cause nerve impingement and pain.

The most effective medicines include numbing and antiinflammatory steroid medicines, which help reduce swelling and inflammation that can lead to pinched nerves.

Nerve irritation in the lumbar spine causes pain, tingling or numbness in the back and legs.

What are the neuro foramina?

The neuro foramina are openings in the vertebrae where nerves pass. The opening includes a hole through the bone and a gap between the vertebrae that is kept open partly by the disks.

What is a neuroforaminal injection, and why is it helpful?

A neuroforaminal injection places antiinflammatory medicine near the foramina to decrease inflammation of the nerve roots to reduce the pain in your back or legs. The injection may help the injury heal by reducing inflammation. It may provide permanent relief or pain relief for several months while the injury or cause of your pain is healing.
