Dry needling is also called trigger point dry needling or myofascial trigger point dry needling. It is done by acupuncturists, some chiropractors, medical doctors, and some physical therapists (PTs) to treat myofascial pain. The word “myofascial” is made up of the roots “myo” (which refers to muscle) and “fascia” (which refers to the tissue that connects muscle).
Muscles sometimes develop knotted areas called trigger points. These trigger points are highly sensitive and can be painful when touched. They are also often the cause of referred pain (or pain that affects another part of the body). Clinicians push thin solid needles through the skin into trigger points. The needles are used to stimulate the tissue, not to inject medication.

Pain affects how your body moves. It is thought that dry needling changes the way the brain and muscles talk to each other to let the system return to a more normal movement pattern.
A patient may experience different sensations when being needled, muscle soreness, aching and a muscle twitch when a needle is inserted is considered to be a good sign. The needles may be placed deeply or superficially, for shorter or longer periods of time, depending on what type of pain is being treated and how long it has lasted. Shorter periods of time would mean that needle would stay in the muscle for seconds, while longer periods could mean 10 to 15 minutes.
What kinds of pain does dry needling treat?
Dry needling is almost always used as a part of an overall plan that will likely include some type of exercise, manual therapy, heat therapy, and education. Dry needling is used to increase range of motion that may be limited due to muscle tightness or scar tissue. Dry needling may also treat:
- Joint problems
- Disk problems
- Tendinitis
- Migraine and tension-type headaches
- Jaw and mouth problems (such as temporomandibular joint disorders or TMD)
- Whiplash
- Repetitive motion disorders (like carpal tunnel syndrome)
- Spinal problems
- Pelvic pain
- Night cramps
- Phantom pain
- Post-herpetic neuralgia (pain left behind by shingles)
Who should not have dry needling treatments?
- Pregnant women
- People who are not able to understand the treatment
- People who are very afraid of needles
Any patient who is considering dry needling should consult his or her doctor first. This is particularly true for people taking blood thinners and people who are only recently recovering from surgery.
Are there side effects from dry needling?
Most adverse effects have been minor and include:
- Soreness during or after the treatment
- Bleeding at the place where the needle was pushed in
- Fainting
- Fatigue
- Bruising
A very rare side effect from improper needle insertion could be major organ puncture, such as a pneumothorax (collapsed lung) caused by puncturing the lung through needle insertion in the chest.
