Does Acupuncture Hurt? A Retrospective Study on Pain and Satisfaction during Pediatric Acupuncture
“This study showed that acupuncture practically does not hurt in children and adolescents — more than half of patients felt no pain at all during treatment.”
Acupuncture Treatment for Nocturnal Crying in Pediatric Patients: A Systematic Review of Clinical Studies
“This study analyzed research on acupuncture for infants and young children who cry intensely during the night.”
What Is Infant Colic
Infant colic is defined by the Wessel criteria as episodes of inconsolable crying lasting more than 3 hours per day, on more than 3 days per week, in infants younger than 3 to 4 months, who are apparently healthy and well nourished, with no identifiable organic cause. The Wessel "rule of 3s" is the most clinically used diagnostic criterion.
Colic affects 5% to 25% of infants, regardless of feeding type (breast milk or formula). The cause remains uncertain: hypotheses include intestinal dysmotility with gas accumulation, immaturity of the enteric nervous system, microbiota imbalance (reduction of Lactobacillus reuteri), cow's milk protein intolerance, and immature autonomic regulation of the infant. The family impact is significant: parental stress, sleep deprivation, maternal postpartum depression, and, in extreme cases, risk of crying-related violence.
When to Rule Out Organic Cause
Conventional Treatments
Evidence on conventional treatments for infant colic is surprisingly limited. No pharmacological intervention has shown consistent efficacy superior to placebo in high-quality meta-analyses.
INTERVENTIONS FOR INFANT COLIC
| INTERVENTION | EVIDENCE | CONSIDERATIONS |
|---|---|---|
| Lactobacillus reuteri DSM 17938 | Moderate — best available evidence | Reduces crying in breastfed infants; less effective on formula |
| Simethicone | Limited — equivalent to placebo in meta-analysis | Widely used; parents report improvement (nocebo effect?) |
| Maternal dairy-free diet | Moderate in CMPI suspicion | Trial for 2 weeks; consult nutritionist |
| Hydrolyzed formula | Moderate in formula-fed infants with CMPI | High cost; not indicated as standard |
| Soothing techniques | Low — but no risks | Rocking, white noise, non-nutritive sucking |
| Dicyclomine (antispasmodic) | Effective but contraindicated <6 months | Apnea and sudden death reported — DO NOT use in infants |
How Acupuncture Works in Infant Colic
Pediatric acupuncture in infant colic acts through mechanisms that address the proposed pathophysiology: immature autonomic regulation, intestinal dysmotility, and the visceral hypersensitivity of the infant.
Mechanism of Action in Infant Colic
Autonomic Regulation of the Infant
Superficial stimulation of ST-36 → activation of parasympathetic tone → reduction of the state of sympathetic hyperexcitability of the immature autonomic nervous system of the infant.
Modulation of Enteric Serotonin
Normalization of enteric 5-HT release by Meissner's plexus → improvement of intestinal motility → reduction of formation and accumulation of gas in the baby's colon.
Reduction of Neonatal Visceral Hypersensitivity
Low-threshold stimulation activates cutaneous mechanoreceptors → release of endogenous opioids (neonatal beta-endorphins) → reduction of response to the painful visceral stimulus.
Vagal Effect on the Gut-Brain Axis
Vagal activation via ST-36 and SP-6 → regulation of the developing neuro-enteric axis → accelerated maturation of visceral autonomic control.
Scientific Evidence
Studies on acupuncture in infant colic have moderate methodological quality, with difficulties inherent to blinding in pediatric populations.

Modern Approach: Adapted Pediatric Acupuncture
PEDIATRIC PROTOCOL FOR INFANT COLIC
| PARAMETER | SPECIFICATION | RATIONALE |
|---|---|---|
| Main points | ST-36 + SP-6 | Enteric autonomic regulation |
| Auxiliary points | CV-12 (gentle) + LI-4 (brief) | Gastric motility + visceral analgesia |
| Technique | 0.16–0.20 mm needle, 1–3 mm depth | Pediatric shonishin technique |
| Retention time | 5–10 minutes maximum | Infant tolerance |
| Needle-free alternative | Massage with hashiboshi at points | For very small or anxious infants |
| Frequency | 2 sessions/week for 2–3 weeks | Duration of the colic period |
| Baby position | In the caregiver's lap during the session | Maximum safety and comfort |

Frequently Asked Questions
Frequently Asked Questions
With adequate technique and careful indication, pediatric acupuncture has a favorable safety profile in the available literature. Pediatric needles are ultra-fine (0.16 mm), inserted to 1–3 mm depth — only subcutaneous — and removed in 5 to 10 minutes. Clinical trials with hundreds of infants have not reported serious adverse events, although mild events (small discomfort, local skin irritation) may occur. Safety depends critically on the medical acupuncturist's pediatric experience and prior exclusion of organic causes by the pediatrician. No procedure is universally free of risks.
Yes, most cases resolve spontaneously by 3–4 months. Acupuncture does not "cure" colic — it anticipates and accelerates this natural resolution, reducing the suffering of the baby and family stress during the most critical period. It is a temporary intervention with the goal of support.
Studies used 2 sessions per week for 2 to 3 weeks (4–6 total sessions). Since colic has expected natural resolution by 3–4 months, short cycles are sufficient and pathophysiologically appropriate.
Yes. Needle-free shonishin technique — massage with a blunt instrument (hashiboshi) over points — is a valid alternative, especially for very small newborns or parents who do not accept needles. The evidence is smaller than for needling, but the safety profile is even more favorable.
Yes. Acupuncture and L. reuteri DSM 17938 act through complementary mechanisms — the probiotic acts on the microbiome while acupuncture regulates the autonomic nervous system. Combinations tend to be more effective. If there is suspicion of CMPI, exclusion of dairy from the maternal diet for 2 weeks is recommended regardless of acupuncture.
