What this treats
Myofascial pain — pain arising from muscle and the fascia around it — is one of the most common causes of musculoskeletal pain and one of the most frequently overlooked. A muscle under sustained strain develops taut bands containing exquisitely tender points, and those points refer pain in patterns that have been mapped and are consistent enough to recognise.
The referral is what causes the confusion. Trigger points in the gluteal muscles refer down the leg and get investigated as sciatica. Points in the trapezius and levator scapulae refer up into the head and get treated as headache. Points in the masseter refer into the teeth and get investigated by a dentist who finds nothing.
How the injection works
A fine needle is placed directly into the taut band. The mechanical disruption of the needle itself does much of the work — it interrupts the contracted segment and often produces a brief local twitch, which is a good sign. A small amount of local anaesthetic is usually injected to reduce the post-injection soreness.
The immediate effect is the muscle releasing. The useful effect is what that release makes possible.
Why it is part of a plan, not the plan
A muscle in spasm hurts; pain causes guarding, which causes more spasm. That loop is self-sustaining and is difficult to break with stretching alone, because the muscle will not lengthen while it is defending itself.
The injection breaks the loop. What decides whether the pain stays away is what happens in the weeks afterwards — the strengthening, the correction of the mechanics that overloaded the muscle in the first place, the change to how you sit or lift or sleep.
This is the difference between a practice that injects and a physician trained in Physical Medicine & Rehabilitation. Dr. D’Alessio’s speciality is restoring function; the injection is one of the tools that makes restoring it possible.
Practicalities
Each site takes a few minutes. Several can be treated in one appointment. There is no anaesthetic required beyond what is injected, no downtime, and you drive yourself home. Expect some soreness at the sites for a day or two — heat and gentle movement help — and avoid heavy exertion that same day.
