A trigger point injection is a procedure that involves injecting a local anesthetic into a specific area of muscle or tissue where a trigger point is located. The injection is intended to relieve pain associated with the trigger point.
How do trigger points cause pelvic pain?
Trigger points cause pain because they compress or irritate nearby nerves, leading to radiating sensations such as dull aches or burning sensations. In addition, they can reduce blood flow to the muscles surrounding them, causing further tissue damage, which leads to even more pain and discomfort. Some trigger points may also cause spasms which further contribute to pelvic pain.
