Trigger point injections (TPI) are a targeted treatment used to release tight, overactive muscles, often referred to as “knots.” When a trigger point is active, it can restrict movement, alter muscle function, and contribute to ongoing pain.
At Prime, trigger point injections are performed using ultrasound guidance. This allows us to visualize the tissue in real time and place the injection precisely where it’s needed, improving accuracy and safety, especially in sensitive areas such as the neck.
TPI can be used as a stand-alone treatment for acute muscle spasm, such as waking up with a kink in the neck or straining the back while lifting. It can also be used alongside rehabilitation to help address longer-standing movement patterns and support more durable improvements in function.
Conditions that may benefit from trigger point injections include muscular neck and back pain, whiplash or strain injuries, headaches, TMJ pain, plantar fasciitis, Achilles tendonitis, concussion-related symptoms, and muscular pain that has not responded to conservative treatment.
Every patient is different. Some conditions improve significantly with a single treatment, while others benefit from a series of treatments with gradual, stepwise improvement, typically spaced two or more weeks apart.
After treatment, a brief period of soreness or stiffness can occur. Acetaminophen or NSAIDs such as ibuprofen may be used if appropriate. Icing the area, staying well hydrated, and gradually returning to normal range-of-motion activities can help support recovery.
Trigger point injections are an MSP-insured service. There is no cost for the procedure itself. In some cases, the medication used may be billed on a cost-recovery basis.
