A tiny needle is inserted by a medical expert into the patient’s trigger point during the TPI process. In addition to saline or a local anesthetic, the injection could also contain a corticosteroid. The trigger point is rendered dormant by the injection, which also reduces pain. Generally, long-lasting relief can be obtained with a short course of treatment. It only takes a few minutes to administer an injection in a doctor’s office. In a single visit, multiple sites could be injected. In cases where a patient is allergic to a certain medication, a medication-free dry-needle approach may be employed.
