A trigger point injection is an outpatient procedure designed to reduce or relieve pain caused by trigger points, which are small knots that form in muscles or in the fascia tissue leading to pain caused by muscle irritation (myofascial pain).
Trigger point injections are used to treat many muscle groups, especially those in the arms, legs, lower back, and neck. They can be used to treat fibromyalgia and myofascial pain syndrome.
Trigger point injections are used to break-up knots with the use of lidocaine (a local anaesthetic) or through dry needling.
What You Can Expect
You will sit or lie down for the procedure. Dr. Panjwani will press on your muscle to identify the area where you have pain. Then she will insert a small needle into the area and inject lidocaine.
You can have several trigger points injected during one visit. The procedure only takes a few minutes.
Trigger Point Recovery
You may have temporary soreness or numbness at the injection site. After a trigger point injection, you can actively use your muscle. However, you should avoid strenuous activity for the first few days.
The risk of complication from a trigger point injection is very low. Complications such as bleeding and infection at the injection site are uncommon. However, you may have temporary soreness or numbness at the injection site.
