Dry Needling: What It Is, How It Works, and What to Expect
Dr. Tonia Thornton, DPT
Board-Certified Physical Therapist
Dry needling is one of the most effective tools in modern physical therapy — but it's also one of the most misunderstood. If you've heard about it and wondered whether it's right for you, here's what you need to know.
What Is Dry Needling?
Dry needling is a technique where a physical therapist inserts thin, sterile, solid needles into specific muscles to release trigger points — those tight, painful "knots" that develop from overuse, injury, or chronic tension. It's called "dry" because the needle itself is the treatment; nothing is injected.
How Is It Different from Acupuncture?
This is the most common question we hear. While both use thin needles, the similarities end there:
- Dry needling is based on Western anatomy and neuromuscular science. It targets specific muscles and trigger points identified during a physical therapy assessment.
- Acupuncture is rooted in traditional Chinese medicine and targets meridian points to balance the flow of energy (qi).
Both can be valuable — they're just different approaches with different goals.
What Does It Treat?
Dry needling is most effective for:
- Chronic muscle tightness and trigger points
- Neck and back pain
- Shoulder impingement and rotator cuff issues
- Tennis elbow and golfer's elbow
- TMJ-related muscle tension
- Hip and glute tightness
- Plantar fasciitis and calf tightness
- Post-surgical stiffness
What Does It Feel Like?
The needles used in dry needling are extremely thin — much thinner than a hypodermic needle. Most patients feel a slight prick on insertion, followed by a deep aching or "twitch response" when the trigger point is engaged. That twitch is actually a good sign — it means the tight band of muscle is releasing.
Some soreness is normal for 24-48 hours after treatment, similar to what you'd feel after a deep tissue massage. Most patients report significant improvement in pain and mobility within 1-2 sessions.
What Happens During a Session at Peak Swing PT
Every dry needling session at Peak Swing is 60 minutes. Dr. Thornton will palpate your muscles to locate trigger points, insert needles into the affected areas, and may use gentle manipulation to enhance the release. The session also includes assessment of why those trigger points developed in the first place — so the underlying issue gets addressed, not just the symptom.
Is Dry Needling Safe?
When performed by a licensed, trained physical therapist, dry needling is very safe. Dr. Thornton uses single-use, sterile needles and follows strict protocols. Minor bruising or soreness is the most common side effect. Serious complications are extremely rare.
