How is a Piriformis Injection Done?
To begin, the patient will lay on the least sore side with the knees bent toward the chest. One of our physicians will push on the buttock region to find the trigger point that is the most painful – this is where the sciatic nerve and piriofrimis muscle is the most inflamed or tight. The skin is then numbed with local anesthetic. The physician will then insert a needle into the piriformis muscle. A small electric current will pass through this needle into the muscle. Patients may feel a “thumping” sensation in the buttock that can cause a mild contraction of the muscle. This procedure will help the physician find your most painful spot. Once the most painful spot is found, a piriformis injection of steroid and anesthetic is inserted into the area to reduce inflammation.
Following the procedure, the injection site will be covered with a bandage and ice may be applied. Most patients report a decrease in pain within 3 to 7 days. Continuing home remedies such as ice and heat can help with the recovery process. Physical therapy may also be prescribed to assist with healing.
What are the Risks Involved with a Piriformis Injection?
This procedure is very safe and there is little risk. Some side-affects can include temporary pain or infection and possible sciatic nerve block, which can cause temporary leg weakness. Our physicians will discuss these risks with patients in detail.
