Trigger PointsTrigger Point Injections (TPI) are medications administered to relax tender and tight clusters of muscle known as trigger points.
Trigger points consist of many sensitive spots in various parts of the body. These injections only require minimal invasion to the body.

The doctor first gives the patient an injection of painkillers known as Marcaine to the affected area. The common areas of the body affected by trigger point muscle pain are the lower back, neck, arms, or legs.

Some common side effects include injection site bleeding, worsening of pain, and nerve damage. TPI can also be used to treat Fibromyalgia and tension headaches.

As a result, the damage to muscle and connective tissue which results in trigger points can occur several ways. It can happen as the result of:

  • First Repetitive overuse injuries (using the same body parts, in the same way, hundreds of times on a daily basis) from activities such as typing/mousing, handheld electronics, gardening, home improvement projects, work environments, etc.
  • Consequently sustained loading as with heavy lifting, carrying babies, briefcases, boxes, wearing body armor or lifting bedridden patients.
  • Habitually poor posture due to our sedentary lifestyles, de-conditioning, and poorly designed furniture
  • Muscle clenching and tensing due to mental/emotional stress.
  • A direct injury such as a blow, strain, break, twist or tear. Think car accidents, sports injuries, falling down stairs and the like.
  • Finally, trigger points can even develop due to inactivities such as prolonged bed rest or sitting.
