Overview
About Trigger Point Injection
A trigger point is a hyperirritable, tender nodule within a taut band of skeletal muscle that causes local pain and can refer pain to distant areas. Common trigger points occur in the neck, shoulder, back, and hip muscles. Injecting a local anaesthetic or a small amount of steroid directly into the trigger point relaxes the muscle knot, breaks the pain cycle, and restores normal function.
Key Benefits
Immediate relief from chronic muscle pain and painful muscle knots
Eliminates referred pain patterns caused by active trigger points
Restores normal muscle function and range of motion
Quick OPD procedure — results felt within minutes to hours
Can be combined with physiotherapy for long-lasting results
Frequently Asked Questions
What is a trigger point?
A trigger point is a tight, tender knot within a muscle that is painful when pressed and can cause pain to radiate to other areas. Common locations include the upper trapezius (shoulder/neck), gluteal muscles (buttock/hip), and paraspinal muscles (back).
Is the injection painful?
There may be a brief twitch or cramping sensation as the needle enters the trigger point — this is normal and indicates the correct location. Discomfort is minimal and short-lived.
How many sessions are needed?
Many patients get significant relief after 1–2 sessions. Chronic or multiple trigger points may require 3–5 sessions spaced 1–2 weeks apart, combined with physiotherapy.
What is the difference between trigger point injection and a steroid injection?
Trigger point injections target muscle knots with local anaesthetic (sometimes with a small amount of steroid). They differ from joint injections which are placed directly inside the joint for arthritis or inflammation.
What should I do after a trigger point injection?
Gentle stretching of the treated muscle within 24 hours is recommended to maintain the muscle relaxation achieved by the injection. Avoid strenuous activity for 24 hours.
