What are Trigger Point Injections (TPI)?

A trigger point is a knot or tight band of muscle and soft tissue like fascia. Trigger points can be felt under the skin and may be painful when touched. TPI involves the insertion of a needle into trigger points causing them to relax.  

At CHANGEpain, we use 0.9% saline solution, which has the same concentration as your blood. We use saline rather than other medications such as lidocaine or steroids to reduce possible side effects.  There is evidence that saline injections have effective outcomes in pain reduction. 


Trigger points can irritate nerves and cause pain. Scar tissue, loss of movement and weakness may develop over time if they are left untreated. Trigger Point Injections have been proven to be an effective method of relaxing muscles and improving soft tissues, and reducing pain.

How does it work?


What does treatment involve?

Your doctor will physically examine you and ask you where you pain is.  The doctor will insert a needle into the points he or she identifies as causing the pain problem. Often the needling sites are not where pain is felt. For example, low back pain often comes from trigger points in the abdomen rather than the back.  The body is all connected!

After TPI, we expect that your muscles and fascia will relax and your pain will decrease.


How much does it cost?

Trigger Point Injections are covered by MSP. 


Risks mainly depend on the injected areas. Your doctor will discuss these risks with you. Side effects may include:

  • pain during needle insertions
  • bleeding
  • bruising
  • fatigue
