Trigger Point Injections
Trigger point injection (TPI) may be an option for treating pain in some patients. TPI is a procedure used to treat painful areas of muscle that contain trigger points, or knots of muscle that form when muscles do not relax. Many times, such knots can be felt under the skin. Trigger points may irritate the nerves around them and cause referred pain, or pain that is felt in another part of the body.
During The Procedure
This procedure only takes a few minutes. Numbing medication and then steroids are quickly injected into the targeted muscle.
Discomfort during the procedure should be minimal since the injection site is numbed with a local anesthetic using a very thin needle during the performance of the block. Afterward, the patient rests briefly in the office. Most people can drive themselves home, but should take it easy and not return to work or other taxing activities until the next day.
If a patient desires further sedation, that is certainly available. Usually this isn’t necessary and sedation does increase recovery time. Also a patient must then be driven home by a second party.
Degrees of response vary widely. Patients should report their degree of pain relief to their physician so any further treatment can be planned with accuracy.
