Piriformis Blocks

Piriformis blocks target the piriformis muscle, which is located in the lower buttocks and just above the tailbone. The straining of this muscle is referred to as piriformis syndrome. Tightness in the area can contribute to sciatica.

How it Works

A piriformis block consists of a local anesthetic and a steroid. By injecting the area around the sciatic nerve in the piriformis muscle, irritation and inflammation of the nerve caused by muscle strain is reduced.

This pain management injection takes about 20 to 30 minutes and is performed using x-ray imaging in order to target a precise area.


The local anesthetic allows you to experience immediate relief, but this will wear off in a few hours. More long term relief occurs in three to seven days when the steroid begins working.

Redness and soreness at the injection site is common, but temporary. Other risks, like infection and bruising, are not common. You will be able to return to your regular activities the following day.
