What medications are used in trigger point injections?

- BOTOX – Botulinum toxin type A.
What are trigger points?
Trigger points, also called muscle knots or trigger sites, are hyperirritable spots in the muscle tissue that are associated with taut bands of muscle fibers. Trigger points are small contraction of tissue that cause pain. Pressing on a trigger point can lead to local pain, referred pain, or a twitch response.
How do trigger point injections work?
Trigger point injections have been used in medicine for over 50 years. Experts believe these injections offer physical and psychological symptom relief. The safety and efficacy of TPIs has been investigated in many clinical studies.
What conditions are associated with trigger points?
Trigger points can occur alone or in combination with other medical conditions. They are associated with:
- Myofascial pain syndrome
- Chronic neck pain
- Chronic back pain
- Cluster headaches
- Chronic tension-type headaches
- Chronic migraine
- Chronic shoulder pain
Will I need to prepare for the trigger point injections?
The trigger points are injected in the doctor’s office, and no sedative or local anesthetic is used. The procedure is done with you lying face-down or sitting on the procedure table. Because bleeding can occur, you should notify the doctor if you are taking anything that thins the blood. This include nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin, Coumadin, Plavix, and Ticlid.
How are trigger point injections done?
After you meet with the pain management specialist, the doctor will evaluate you and decide if trigger point injections will help. The nurse will go over procedure risks and benefits, have you sign a consent form, and make you put on a procedure gown. The doctor will clean the skin with an antiseptic and palpate the trigger points. After identifying all the regions, the skin is marked with a skin pen. The doctor then injects the region with a tiny needle, instilling the medication. Small spot band-aids are applied to injection sites.
What can I expect after the TPIs?
After the doctor injects your trigger points, you may experience some mild bruising and tenderness at the multiple injection sites. Over the next few hours and days, you will experience pain relief. If a corticosteroid is used, the anti-inflammatory effects will not be noticed for 2-3 days.
Are trigger point injections effective?
In a study involving 91 patients with myofascial pain, researchers found that TPIs had a 93% success rate. The injections involved use of ultrasound guidance for needle placement, and no medication was injected (dry needling). In a 12-week study involving trigger points in shoulder muscles, researchers found that the therapy reduce pain and improved shoulder function. In a study where patients with fibromyalgia were treated using TPIs, doctors found that the injections improved quality of life and range of motion. In addition, TPIs have been used for chronic tension-type headache, chronic migraine, and cluster headaches with success.
