The good news is that trigger points are treatable, even after years of irritation/pain. There are different methods to treat trigger points; for example, trigger point injection, manual trigger point therapy and dry needling. The key for all of these therapies is isolating and locating the trigger point.
Trigger point injection (TPI) is a procedure where a health care professional inserts a small needle into the patients trigger point. The injection contains medication, such as local anesthetic (+/- a corticosteroid), or botulinum toxin.
Botulinum toxin injections have undergone extensive evaluation and current understanding of the nature of muscle-induced pain and research regarding neuromuscular blockade and/or inhibition of nociception in such conditions, is being investigated by many centers.
Manual trigger point therapy is the treatment of muscles and connective tissues with specific hands on techniques. Dry needling, is where a sterile acupuncture needle is used to puncture the muscle membrane, change local circulation and to interrupt the referred pain.
