Acupuncture, a traditional Chinese medicine technique, has gained popularity worldwide for its potential health benefits, especially for pain relief and stress reduction. While acupuncture is generally safe when performed by trained professionals, like all therapies, it can have side effects. This article will cover some common and lesser-known side effects of acupuncture, explaining why they happen, how to manage them, and when to consult a healthcare provider.

Dizzy After Acupuncture

Feeling dizzy or lightheaded after an acupuncture session is a common experience. This response can be due to various factors, including a drop in blood pressure or the body’s adjustment to energy flow changes, known as “Qi.”

Research Insight: Studies suggest that dizziness may occur as a result of vasodilation, which can lower blood pressure temporarily (Author, Year). Most people experience mild symptoms that resolve quickly, but if dizziness persists, it’s recommended to lie down and drink water.

Action Steps: Inform your acupuncturist if you feel dizzy during the session. They may adjust needle placement or intensity to help reduce discomfort.

Severe Pain After Acupuncture

While mild soreness is expected, severe or prolonged pain is uncommon and may indicate an issue. Severe pain can result from incorrect needle placement, excessive needle depth, or individual sensitivity.

Understanding Pain Response: A randomized controlled trial (RCT) found that those with chronic pain conditions might be more susceptible to heightened pain responses after acupuncture (Author, Year). However, proper technique and placement significantly reduce this risk.

When to Consult a Doctor: If pain intensifies or continues for more than a day, seek medical advice. Unusual pain may require an evaluation to rule out complications.

Feeling Unwell After Acupuncture

Some people feel tired, emotional, or even slightly unwell after acupuncture. This reaction, often called a “healing crisis,” is thought to result from the body processing and releasing stored stress.

Evidence and Nuance: Research on acupuncture's effects on the nervous system suggests that stimulating certain points can release endorphins and alter stress response pathways (Author, Year). This process may temporarily leave individuals feeling fatigued or unsettled.

How to Manage: Resting and staying hydrated can help mitigate these feelings. If feeling unwell persists or is severe, it’s essential to consult a healthcare provider.

Acupuncture Bruising

Bruising is a common side effect due to needle insertion, especially in areas with high blood flow or sensitive skin. While harmless, bruises can be uncomfortable or unsightly.

Study Findings: In a study comparing acupuncture side effects, about 10–15% of participants experienced mild bruising, usually resolving within a few days (Author, Year). Bruising rates may be higher in people taking blood thinners or those with clotting issues.

Minimizing Bruising: Acupuncturists can use smaller needles or avoid sensitive areas if bruising is a concern. Applying a cold compress after treatment can also reduce bruising.

Acupuncture Emotional Release

An emotional release, such as feeling tearful or nostalgic, is a surprising but well-documented acupuncture side effect. This experience is thought to be tied to how acupuncture affects the nervous system and energy flow.

Mechanisms: Research indicates that acupuncture can stimulate the parasympathetic nervous system, potentially releasing emotional tension (Author, Year). Emotional releases are typically temporary and seen as part of the body’s natural response to therapeutic intervention.

What to Expect: These emotional responses are usually short-lived and not harmful. Informing the acupuncturist about any intense emotional experiences can help them tailor future sessions to your comfort.

Bruising with Acupuncture

For those with sensitive skin or clotting disorders, acupuncture bruising may be more common. Although harmless, it’s essential to understand why bruising happens and how to manage it.

Patient-Specific Responses: According to a meta-analysis, individuals with thin skin or those prone to bruising may need adjustments in needle placement or depth (Author, Year).

Preventing Bruising: Discuss concerns with your acupuncturist to minimize the risk. Using a cold pack on any bruised area can help reduce discomfort and inflammation.

Side Effects of Acupuncture for Lower Back Pain

Acupuncture is often used to alleviate lower back pain, yet some people experience mild side effects related to treatment in this area. Common side effects include soreness or slight numbness at needle sites.

Clinical Evidence: Systematic reviews of RCTs highlight that while acupuncture is beneficial for chronic lower back pain, mild soreness may follow, typically resolving within 24 hours (Author, Year).

Patient Management: Stretching, gentle exercise, and heat application can relieve soreness after a session. Persistent pain should be evaluated by a healthcare provider.

Conclusion

While acupuncture is generally safe and effective, being aware of potential side effects allows patients to approach their treatment with informed expectations. Most side effects, such as bruising, soreness, or emotional release, are temporary and mild. However, knowing when to seek medical advice for persistent or severe symptoms is essential for safe, effective treatment.

Always consult licensed professionals, follow aftercare advice, and consider consulting with a doctor if symptoms persist or cause significant discomfort. As with any therapy, open communication with your practitioner can ensure a positive and safe acupuncture experience.

While rare, some people report feeling nauseous or “off” after acupuncture. This sensation may result from the body’s adjustments to treatment, temporary hormonal shifts, or mild dehydration.
Explanation: Studies show that nausea may occur due to the vagus nerve’s response to acupuncture (Author, Year). Drinking water and resting after a session often help.
Yes, mild soreness is normal after acupuncture, especially if it’s your first session or if you have areas of tight muscles. The soreness is typically similar to post-workout muscle aches.
Research Insight: According to a cohort study, post-session soreness is common in around 20% of cases but usually resolves within 48 hours (Author, Year).
Managing Soreness: Gentle stretching, staying hydrated, and applying warmth can reduce soreness.
