Piriformis muscle injections are used to determine the cause of buttock and sciatica type pain.

Piriformis syndrome is a rare condition in which a person has the sciatic nerve passing through the fibers of the piriformis muscle that is located in the buttock. This causes the sciatic nerve to become inflamed due to being constantly pressed due to its anatomical location.

When a person with piriformis syndrome has an inflamed sciatic nerve, intense pain in the right leg is common, because this is usually the most affected side, in addition to pain in the buttock, numbness and a burning sensation. To confirm the piriformis syndrome, the physiotherapist usually performs some tests to rule out other situations and check the severity, and then the most appropriate treatment can be indicated.

The symptoms of piriformis syndrome are related to the compression of the sciatic nerve by the piriformis muscle and can be seen mainly in the lumbar region, buttocks and thigh, the main ones being:   

  • Stinging pain;
  • Burning or tingling sensation in the buttocks or behind the thigh;
  • There may be pain in the side of the leg and the top of the foot;
  • Pain is worse when sitting and crossing the leg;
  • The first crisis can appear in pregnancy, due to the increase in weight and size of the belly;
  • It is common for a person to walk with a limp during a sciatica attack;
  • Symptoms such as leg weakness, and numbness in the buttock or leg may be present.

Some situations that can favor the piriformis syndrome include the increase of the piriformis muscle due to the practice of exercises for the buttocks, contraction of the buttocks, sitting down or a traffic accident, or anything that leads to a blow in the buttocks region, generating a hematoma and that compresses the sciatic nerve.  

These muscle injections are both diagnostic and therapeutic! Our team is able to determine the cause of your back pain AND provide you with relief from the pain.

These injections eliminate pain temporarily by paralyzing the piriformis muscle and stopping the muscle spasm. If the piriformis muscle is injected and your pain goes away for several days, then it is very likely that a portion of your pain is caused by piriformis syndrome. Once we know what structure is causing your pain, we can begin to explore options for treating the condition!
