Tunnel injections consist of a corticosteroid and local anesthetic, and can be used in the cubital, radial, carpal, and tarsal tunnels in order to reduce inflammation and provide pain relief.
How it Works
Tunnel injections take about 10 to 20 minutes. The combination of the local anesthetic and the steroid help to reduce swelling and relieve pressure around the targeted nerve, resulting in relief from pain and sometimes weakness.
Tunnel injections may be used for:
- Cubital tunnel syndrome – This is a pinching of the ulnar nerve located at the elbow that results in numbness, pain, tingling, and a weak grip.
- Radial tunnel syndrome – This is caused by pressure on the radial nerve, which runs from the neck all the way into the hand. The radial tunnel is located near the outside of the elbow and can become inflamed from overuse.
- Carpal tunnel syndrome – This is caused by pressure on the nerve that runs from the forearm into the palm.
- Tarsal tunnel syndrome – This condition is caused by compression on the tibial nerve, which runs from the ankle into the foot.
You will feel immediate relief from the anesthetic, but this will wear off after a few hours. Long term relief comes a few days later from the steroid. The injections can be repeated if needed.
Soreness and redness at the injection site is common, but temporary. You will be able to resume normal activities the next day.
