The Drawbacks and Risks of Trigger Point Therapy

By Your Health Magazine Health Information Team

The main disadvantages of trigger point therapy are temporary soreness, bruising, symptom flare-ups, inconsistent results, and the possibility that relief will be short-lived. Forceful manual pressure can injure vulnerable tissues, while dry needling and trigger point injections add risks such as bleeding, infection, nerve injury, and—in rare cases involving the chest or upper back—a punctured lung. Results also depend heavily on identifying the correct source of pain and using an appropriately trained practitioner.

Not All Trigger Point Treatments Have the Same Risks

“Trigger point therapy” may refer to several treatments aimed at sensitive or tight areas within muscles. The potential drawbacks depend on the method being used.

Treatment	How It Is Performed	Main Drawbacks
Manual trigger point therapy	Sustained pressure, massage, or soft-tissue manipulation	Soreness, bruising, pain aggravation, and possible tissue injury from excessive force
Dry needling	A thin needle is inserted into muscle without injecting medication	Pain, bleeding, bruising, infection, faintness, nerve injury, and rare organ injury
Trigger point injection	A clinician inserts a needle and may inject a local anesthetic or another medication	Injection-site discomfort, numbness, bleeding, infection, medication reactions, and blood vessel injury

Before treatment, ask the practitioner to explain exactly which technique is being proposed. Manual pressure, dry needling, and medication injections should not be treated as interchangeable procedures.

Common Short-Term Side Effects

Some discomfort during treatment is expected because the practitioner is pressing or needling an already tender area. Afterward, a person may experience:

Muscle soreness or aching
Temporary worsening of the original pain
Bruising or mild swelling
Skin tenderness
Fatigue, lightheadedness, or headache
Reduced comfort with exercise or daily movement for a short period

Mild soreness often settles, but severe or progressively worsening pain should not be dismissed as proof that the treatment is “working.” The National Center for Complementary and Integrative Health reports that the overall risk associated with massage is low, but rare injuries have been reported after vigorous massage, including nerve injury, fracture, and complications involving a blood clot.

Benefits Can Be Uncertain or Temporary

One of the most important disadvantages of trigger point therapy is that it does not consistently address the underlying cause of pain. Muscle tenderness may be influenced by repetitive strain, poor movement patterns, reduced activity, stress, joint problems, nerve irritation, an injury, or another medical condition. Pressing a tender point may temporarily alter symptoms without correcting these contributing factors.

Trigger point identification also relies largely on examination findings such as localized tenderness, a tight band of muscle, referred pain, or a muscle twitch. Research has used varying criteria to define and diagnose trigger points, which can make treatment selection and study results difficult to compare.

Some people obtain meaningful relief, while others notice little or no improvement. Benefits may fade and lead to repeated appointments, adding time and expense. For persistent symptoms, trigger point work is generally more useful as one part of a broader plan that may include appropriate activity, rehabilitation, sleep support, and evaluation of the pain’s cause. MedlinePlus provides additional information about the broader evaluation and management of chronic pain.

Needle-Based Therapy Has Additional Risks

Dry needling breaks the skin and reaches deeper tissues, so it carries risks that do not apply to ordinary manual pressure. Minor reactions such as pain, bruising, and small amounts of bleeding are relatively common. A systematic review of adverse events associated with dry needling concluded that serious complications are uncommon but can occur.

Potential complications include infection, excessive bleeding, nerve injury, prolonged symptom aggravation, and accidental injury to nearby structures. Needling around the neck, shoulder, chest, or upper back presents a rare risk of pneumothorax, which occurs when a needle enters the area around a lung and causes it to collapse partially or completely.

Trigger point injections introduce additional considerations because they may contain a local anesthetic or another medication. Possible complications include an allergic reaction, temporary numbness, blood vessel injury, and medication-specific effects. An overview of trigger point injection risks and side effects emphasizes the importance of discussing medications, symptoms, and overall health with the treating clinician beforehand.

Who Should Use Extra Caution?

Trigger point therapy may need to be modified, postponed, or avoided in certain situations. Consult a qualified healthcare professional before treatment if you have:

A bleeding disorder, low platelet count, or treatment with a blood-thinning medication
Fragile bones or severe osteoporosis
An open wound, burn, rash, or skin infection in the treatment area
A recent fracture, surgery, or significant injury
A known or suspected blood clot
Reduced sensation that could prevent you from judging pressure or pain accurately
Pregnancy, cancer, significant immune suppression, or another condition requiring treatment modifications
An allergy to an anesthetic or other substance proposed for an injection

Self-treatment also has limits. Aggressively pressing a ball or hard tool into the neck, abdomen, spine, or an area with numbness can cause injury or obscure symptoms that require assessment. Gentle mobility may be more appropriate for some muscle-related discomfort; for example, carefully performed seated piriformis stretching techniques may be considered when suitable for the individual.

How to Reduce Avoidable Problems

Choose a licensed or otherwise appropriately credentialed professional with training in the specific technique.
Describe your medical conditions, medications, allergies, previous procedures, and history of unusual bleeding or fainting.
Ask what benefits are realistically expected and how progress will be measured.
Request an explanation of needle placement and risks before consenting to dry needling or an injection.
Speak up immediately if treatment causes sharp, electrical, burning, or intolerable pain.
Reconsider the plan if repeated sessions produce no functional improvement or consistently worsen symptoms.

When to Seek Care

Arrange an evaluation with a primary care clinician, physical therapist, physiatrist, sports medicine professional, or pain specialist if pain is persistent, unexplained, worsening, or interfering with normal activity. Seek prompt medical attention for fever, spreading redness, drainage, substantial swelling, progressive weakness or numbness, uncontrolled bleeding, or severe pain after treatment.

After needling near the chest, shoulder, neck, or upper back, sudden chest pain, coughing, shortness of breath, bluish skin, fainting, or unusual difficulty breathing requires emergency care. New loss of bladder or bowel control, numbness around the groin, or rapidly worsening limb weakness also warrants immediate evaluation rather than further trigger point treatment.

Trigger point therapy may be helpful for selected muscle-related pain, but it is not risk-free or universally effective. Understanding the specific technique, its limitations, and the reason for the pain makes it easier to decide whether its potential benefits justify the drawbacks.
