Trigger point injections target painful muscle knots to relieve tension and improve movement. Learn how they work and what to expect.

Key Takeaways
- That stubborn knot in your neck, shoulder or back that seems to tighten and ache no matter how much you stretch - it may be a trigger point. When these knots persist and limit movement, a trigger point injection is one option our pain medicine team may discuss. Here is how it works.
What is a trigger point?
A trigger point is a tight, tender band or knot within a muscle. Pressing on it can reproduce your pain, and sometimes the pain spreads to a nearby area - for example, a knot in the shoulder that sends ache up into the head. Pain coming from muscle in this way is often called myofascial pain ("myo" = muscle, "fascia" = the connective tissue around it).
Trigger points can develop from posture, repetitive strain, overuse, stress, or as a companion to other pain problems.
What is a trigger point injection?
A trigger point injection is a small injection placed directly into the knot. Depending on the plan, it may contain local anesthetic, or in some cases the needle itself is used to release the tight band. The aim is to relax the muscle, ease tenderness, and help you move more freely so you can return to activity and stretching.
At YOUNIFY Clinic this is performed by our medical team, and ultrasound may be used to help guide the needle accurately where appropriate.
How the procedure is done
1. The doctor examines the muscle and locates the tender knot.
2. The skin is cleaned.
3. A fine needle is inserted into the trigger point; ultrasound guidance may be used.
4. The medicine is delivered, or the band is gently released with the needle.
5. The needle is removed and the area is checked.
The procedure is quick and needle-only. There are no incisions, and most patients go home the same day - often within a short time of arriving.
What to expect afterward
Experiences vary:
- Some people feel a brief muscle twitch as the knot is treated - this can be a normal response.
- The area may feel sore or bruised for a day or two.
- Applying gentle heat and continuing light movement is often advised; your team will give specific guidance.
Trigger point injections are usually most helpful when combined with stretching, posture care, physical therapy and activity - addressing why the knots keep forming, not just the knot itself.
What results to expect
The aim is to relieve pain and improve movement. Response and how long relief lasts vary between individuals. Some people gain useful relief from one session; others benefit from a small number of treatments as part of a broader plan. Trigger point injections are an option within your care, not a standalone fix.
Who might consider them
They may be discussed when:
- A specific, reproducible muscle knot is contributing to your pain.
- Stretching, massage and self-care have not fully settled it.
- Muscle tension is limiting your movement or rehabilitation.
Suitability is decided after an assessment, since muscle pain can overlap with other sources such as joints or nerves.

Frequently Asked Questions
Does the injection hurt?
There can be brief discomfort or a twitch as the knot is treated. Many people find it tolerable, but experiences differ.
How many injections will I need?
It varies. Some people need only one; others have a few as part of a plan. Your team will advise after reviewing your response.
Will the knots come back?
They can, especially if the underlying cause - posture, strain, stress - is not addressed. That is why the injection is paired with rehabilitation and self-care.
