A trigger point injection can help soothe myofascial pain, especially in your neck, shoulder, arms, legs, and lower back.
Trigger points are painful “knots” in your muscles that can be very sensitive to touch/pressure. They may form after acute trauma or by repetitive micro-trauma, leading to stress on muscle fibers. It causes the muscle fibers to remain in a state of contraction. Sometimes you can feel these knots when you rub your muscle.
Trigger point injections commonly involve injections of local anesthetic with or without corticosteroid, botulinum toxin, or without any injection substance (dry needling).
Trigger point injections commonly treat the following:
- Muscle strain.
- Structural causes of pain.
- Issues with your spinal column causing back pain, such as degenerative arthritis, a herniated disk, or spinal stenosis.
- Radiculopathy (pain from a pinched nerve).
