Trigger Point Injection

A trigger point injection is an injection of medication into a tight bundle of muscles called trigger points.

The physician is able to find these painful muscles during an exam. 

In some cases muscle tightness continues and does not respond to usual treatments such as ice and heat, physical therapy or muscle relaxants.

To help relax the muscle, we inject either a local anesthetic (numbing medicine) or a combination of a local anesthetic medication and a steroid medication. 

  • The procedure is usually done in the office.
  • The physician locates the trigger points.
  • Your child's skin will be cleaned with chlorhexidine and a small needle will be inserted into the trigger points.
  • We usually inject two to four trigger points in a session. We will perform up to 10, but they can be painful, so we limit the number for your child's comfort.
  • It is very important that you or your child tell the physician when the needle contacts the painful area as this is where the medicine will be injected. The discomfort will be temporary. 

There are several possible complications; however, the risk is extremely low. They include mild skin irritation, mild bleeding and infection.

Your child can return to normal activities the next day. 

You may find that your child's pain gets worse initially. Your child's doctor may order a small amount of pain medication for the first two days until the injected medication begins to work. This occurs because placing a needle into an irritated muscle causes more irritation.

The pain should begin to decrease about two days after injection.

About three days after the injection, call our office to discuss how your child is doing. You may also call us for questions or concerns at 1-513-636-7768. 

Call the doctor if your child develops fever and redness at the site of injection.
