A trigger point injection is a simple, in-office procedure used to treat painful “knots” in your muscles called trigger points. These knots form when a muscle becomes tight and won’t relax, and they can cause aching, stiffness, or pain that sometimes spreads to other areas of your body. During the procedure, your doctor uses a small needle to inject medication directly into the trigger point to help release the knot and relieve your pain.
How is the procedure done?
- Your doctor will feel the affected area to locate the tight, tender knot in your muscle.
- The skin is cleaned, and a small needle is inserted directly into the trigger point.
- A local anesthetic (numbing medicine), sometimes combined with a small amount of anti-inflammatory steroid, is injected. In some cases, a technique called “dry needling” is used, where the needle itself helps break up the knot without injecting any medication.
- The procedure typically takes only a few minutes and is done right in the office, with no surgery or sedation needed.
Why might my doctor recommend trigger point injections?
Your doctor may suggest this treatment if you have:
- Persistent muscle pain or tightness in the neck, shoulders, upper back, or lower back
- Tension headaches or pain that starts in the neck and travels to the head
- Muscle pain that has not improved with stretching, massage, or over-the-counter pain relievers
- Myofascial pain syndrome (chronic pain caused by trigger points)
- Fibromyalgia-related muscle tenderness
- Limited range of motion or stiffness due to muscle knots
What should I expect after the procedure?
- You may feel immediate relief from pain once the numbing medicine takes effect.
- Some mild soreness or a dull ache at the injection site is normal and usually goes away within a day or two.
- Applying ice or a warm compress to the area and gentle stretching can help with any soreness.
- Most people can return to their normal activities right away, though your doctor may recommend avoiding heavy lifting or intense exercise for the rest of the day.
How many treatments will I need?
Some patients feel significant relief after just one injection, while others may benefit from a series of treatments spaced a few weeks apart. Your doctor will work with you to create a plan based on your specific needs, which may also include physical therapy, stretching exercises, or other treatments to prevent the trigger points from returning.
Is it safe?
Yes. Trigger point injections are very safe and well-tolerated. Serious side effects are rare. The most common side effects are temporary soreness or a small bruise at the injection site. Be sure to let your doctor know if you are on blood thinners, have an infection in the area, or are allergic to any medications.
