What Is Dry Needling?
Dry needling is a minimally invasive procedure in which practitioners insert ultra‑thin solid needles into muscle trigger points, localized knots, or taut bands known for causing pain and limiting movement.
Unlike injections, no medication enters the body. Its goal is to treat dysfunctions in muscle and connective tissue while reducing pain. Our McHenry dry needling therapists are trained in functional dry needling to alleviate pain, restore movement, and support muscle recovery.

Key Mechanisms That Explain Dry Needling Pain Relief
Trigger Point Targeting
Trigger points accumulate metabolic waste, become acidic, and sensitize nearby nerves. When left untreated, they limit mobility and provoke local or referred pain.
Local Twitch Response
When a needle penetrates a trigger point, it often triggers a reflexive muscle twitch. This twitch breaks the taut muscle fiber band, causing immediate muscle relaxation and resetting neuromuscular tone.
Improved Blood Flow & Biochemical Changes
A dormant trigger point suffers from poor circulation. Needle insertion disrupts this stagnation. Blood flow increases, bringing oxygen and nutrients while flushing out inflammatory chemicals. Studies show concentrations of pain‑causing biochemicals decline after dry needling
Nervous System Modulation
Dry needling initiates both local and central nervous system responses. It can activate endogenous opioid systems, increase the pressure pain threshold, and reduce central sensitization. This leads to graded pain relief at multiple central levels, from the spinal cord to the brain
Immediate versus Lasting Effects
Patients often notice pain reduction and improved range of motion directly after treatment, but full results may require several sessions. Clinical studies support short‑term benefits in reducing pain and increasing function up to 12 weeks following treatment
Comparing Superficial and Deep Techniques
- Superficial needling: skin‑level insertion up to 10 mm. Easier to administer and carries a very low risk, but may offer milder effects
- Deep needling: inserted into muscle tissue, directly targeting trigger points. More likely to produce local twitch responses and stronger analgesic effects
Role of Electrical Dry Needling
Electrical stimulation can enhance manual dry needling by delivering measurable currents through needles. Lower frequencies may engage endorphin‑mediated pain pathways while higher frequencies influence spinal analgesia. Some trials show that combined electrical stimulation plus exercise or mobilization yields greater long‑term reductions in pain and disability
What Conditions Benefit from Dry Needling
Dry needling can relieve acute or chronic pain from:
- Myofascial pain syndrome
- Trigger‑point related neck, shoulder, back, and TMJ pain
- Tendinitis, sprains, strains, iliotibial band syndrome, and runner’s knee
- Headaches, whiplash, low back pain, and sports injuries
Often used in combination with physical therapy, massage, stretching, exercise, or soft‑tissue mobilization for optimal outcomes.
What to Expect During Treatment
- Providers locate trigger points through assessment and palpation
- A thin needle is inserted into or near the point
- The needle may remain for seconds to minutes, depending on technique and goal
- Muscle may twitch involuntarily; this response indicates effectiveness
- Some discomfort or soreness may follow, resembling post‑exercise fatigue
Safety, Risks, and Contraindications
Dry needling is low‑risk when performed by licensed providers trained in anatomy and sterile technique. Common side effects include temporary soreness, bruising, fatigue, or mild bleeding. Rare complications may include pneumothorax, nerve injury, or infection
Avoid treatment if you have an active infection at the needle site, bleeding disorders, compromised immunity, needle phobia, or pregnancy; always consult your provider first
FAQs
How soon will I feel pain relief?
Many patients report immediate improvements in pain and movement. Full benefits often appear after several sessions over days to weeks
Is dry needling painful?
Needles are ultra‑thin. Many feel only a light pinch. Sensations vary. Muscle twitching may cause brief discomfort. Soreness afterward is expected
Is it different from acupuncture?
Yes. Dry needling is rooted in Western anatomy and neurophysiology. It targets defined muscle dysfunctions rather than energy meridians and is applied by physical therapists or physicians. Acupuncture uses traditional Chinese medicine approaches
How many sessions are needed?
Depends on the severity and location of trigger points. Some require only one, while others benefit from 3–6 sessions paired with therapy and exercises
