A knot under the shoulder blade can ache for weeks, even after stretching, heat, and a good massage. When a knot won’t release on its own, two needle-based treatments often come up. Both aim a needle at the same tight spot in the muscle.
The key difference comes down to medication. Trigger point injections deliver a small dose of local anesthetic into the knot. Dry needling uses a thin, solid needle with nothing injected. That one detail shapes who performs each treatment, how the visit feels, and how you feel the next day.
What Are Trigger Points?
Trigger points are small knots of tight muscle tissue that feel tender when pressed. They often form in the neck, shoulders, upper back, lower back, and hips. Some stay local, while others irritate a nerve and refer pain to another part of the body.
A trigger point usually shows up as one or more of these signs.
- A firm, sore spot. The knot feels harder than the surrounding muscle and aches under pressure.
- Pain that travels. The ache appears away from the knot, often down an arm or a leg.
- Tension headaches. Knots in the upper trapezius, between the neck and shoulder, can contribute to frequent headaches.
- Limited motion. Turning the head or bending forward feels stiff and restricted.
Most knots build when a muscle works under strain for weeks or months. Long hours at a desk, repetitive work, or a spine out of alignment can keep tissue under constant stress. Over time, the fascia, the thin covering around the muscle, tightens and limits how freely it moves. An injury like whiplash can also leave neck muscles healing in a shortened, guarded position.

Wet Needling vs. Dry Needling
Because the needle carries medication, clinicians often call trigger point injections “wet needling.” Dry needling gets its name because the needle goes in empty.
| Trigger Point Injections | Dry Needling | |
| What goes in | A small dose of local anesthetic | No medication, only the needle |
| Needle type | Hollow injection needle | Thin, solid needle like those used in acupuncture |
| Who performs it | A licensed medical provider | A trained provider, often a physical therapist |
| How it feels | A quick pinch, then numbness | A prick, sometimes a brief muscle twitch |
| Soreness afterward | Usually mild | Often more noticeable for a day or two |
| Where it usually fits | A medical and chiropractic treatment plan | A physical therapy program |
What Happens During an Injection
A medical provider presses along the muscle to locate the knot and cleans the skin over it. They then inject a small dose of local anesthetic into the tight band, often treating several knots in one visit.
Patients usually feel a quick pinch before the anesthetic numbs the area. Mild tenderness or a small bruise at the injection site is common afterward, while infection is rare.
How a Dry Needling Session Works
Most dry needling visits move through four steps.
- Locating the knot. The provider feels along the muscle to find the trigger point.
- Placing the needle. A thin needle is tapped into the skin, often with help from a small plastic guide tube.
- Working the muscle. The provider may move the needle up and down to draw out a brief twitch.
- Removing the needle. Needles stay in anywhere from a few seconds to about 20 minutes before removal.
In Florida, physical therapists can perform dry needling under Section 486.117 of the Florida Statutes. They must first complete a dedicated training course and at least 25 patient sessions. It’s reasonable to ask about that training before your first appointment.
Soreness and Recovery Afterward
After an injection, the anesthetic keeps the treated area comfortable for a while. Soreness tends to be milder than after dry needling, making it easier to return to stretching and rehab.
After dry needling, soreness near the treated spot can last 24 to 36 hours. Any bruising can take up to a week to fade. Providers usually recommend gentle movement and stretching in the meantime.
Which Needling Option Fits Your Pain?
Why choose a needle with no medication in it? Dry needling appeals to people who prefer to avoid medication entirely. It’s usually one part of a physical therapy program built around exercise and stretching.
Trigger point injections tend to suit knots that haven’t released with stretching, massage, or manual therapy. A 2022 review in Pain Medicine found short-term neck trigger point pain eased more with injections. The reviewers rated that evidence as low in certainty and found similar disability scores for both.
Neither needle removes the strain that formed the knot. When posture, repetitive motion, or alignment keeps loading the same muscle, knots tend to come back.
Hands-on myofascial release loosens tight fascia without needles. Between visits, a foam roller helps keep that tissue limber at home. Cold laser and shockwave therapy offer two more drug-free options for soft tissue pain.

Pairing Injections With Chiropractic Care
At Amazing Spine Care, every plan starts with an evaluation that looks for the source of your pain. When a knot hasn’t responded to other care, our medical providers can add trigger point injections to the plan. Before any needle is used, your provider walks you through what the exam found and why an injection may help.
The injection calms the muscle, making adjustments, soft tissue work, and rehab exercises easier to tolerate. Our chiropractors then focus on the alignment and posture habits that strained the muscle in the first place. Because relief varies from person to person, your plan is reassessed as you improve.

Frequently Asked Questions
Do Trigger Point Injections Work Permanently?
Trigger point injections can ease a knot’s pain without guaranteeing permanent relief. Results tend to hold longer when injections are paired with stretching, rehab, and chiropractic care at Amazing Spine Care.
Is There a Downside to Dry Needling?
Dry needling’s most common downside is soreness that can last a day or two, along with possible bruising. People who are pregnant, take blood thinners, or have a weakened immune system should talk with a provider first.
How Often Can You Get Trigger Point Injections?
Trigger point injections don’t follow one fixed schedule. The timing depends on how the knot responds and what your provider finds at follow-up visits. When a knot keeps recurring, Amazing Spine Care looks closer at posture and alignment.
