Administering steroids or a numbing agent at the trigger points, which helps break up any muscle tension in the location of myofascial pain. 


Trigger point injections are used to treat painful areas in the muscle. These painful areas result from the presence of trigger points, which occur from a strained or injured muscle, ligament, or tendon. Trigger points can feel like a knot and are usually very tender when pressure or palpation is applied. They can most commonly occur in the neck, shoulders, and in the lower back. 

Trigger  point  injections  are  performed  in  office  and  usually  lasts  a couple minutes.

Dr.  Sammarone  will  do  a  physical  examination  to  locate  and  identify trigger points.

After  cleansing  the  area  of  injection,  a  small needle is inserted into the trigger point.

The injection administers steroids and/or a numbing agent at the identified trigger points, helping break up any muscle tension, spasm, and/or calcifications. 

What causes the formation of trigger points?
Trigger points may be associated with numerous conditions and a wide range of factors such as:


  • Myofascial Pain Syndrome 
  • Arthritis 
  • Stress
  • Lumbo-sacral Radioculpathy 
  • Muscular Fatigue and/or Trauma 

After the Injection 
Soreness and numbness may be present after the injection. Dr. Sammarone recommends applying an ice pack, and massaging the area of injection for the first 12 hours, applying ice for 20 minutes every two hours, following the procedure.
