Therapeutic modalities, such as ultrasound and manipulative therapy, can be beneficial for some people. However, trigger point injections are considered the most effective way to inactivate a trigger point for prompt symptom relief. The injected medication usually consists of an anesthetic to relax the area and relieve pain. A steroid medication is sometimes included in the injection.
Trigger point injections can be administered at a doctor’s office. The treatment time is short, usually lasting several minutes. You may receive a nerve block or local anesthetic prior to your trigger point injection to prevent pain. To deliver the trigger point injection, your doctor will insert a small needle into the trigger point and inject the medication.
You will be provided with instructions to reduce initial pain and swelling at the treatment site. Trigger point injections are usually followed by physical therapy aimed at pain relief and muscle stretching. In some cases, trigger point injections may be repeated.
