During pregnancy, the main areas to avoid during a foot massage are the inner ankle, the outer ankle, and the space between the thumb and index finger on the hand. These spots correspond to traditional acupressure points believed to stimulate uterine contractions. While gentle foot massage is generally considered safe and can even help reduce swelling, knowing which specific points to steer clear of gives you real peace of mind.
Pressure Points to Avoid on the Feet and Ankles
Traditional Chinese medicine identifies several points on the feet and lower legs that are thought to influence the uterus and reproductive organs. These are the ones prenatal massage therapists are trained to avoid.
Spleen 6 (inner ankle area): Located on the inner lower leg, about four finger-widths above the ankle bone. This is the most commonly cited point to avoid. It sits at the intersection of three energy channels believed to regulate uterine function, and stimulating it is thought to enhance blood flow to the uterus and promote the release of oxytocin, the hormone that drives contractions. Spleen 6 is actually used intentionally during labor to help with pain and progression, which is precisely why it’s avoided beforehand.
Bladder 60 (outer ankle area): Found in the depression between the outer ankle bone and the Achilles tendon. This point has historically been used to promote labor and is thought to aid fetal positioning. Like Spleen 6, it’s sometimes used deliberately after 36 weeks for labor preparation, but is considered off-limits earlier in pregnancy.
Bladder 67 (little toe): Located near the outer edge of the little toenail. This point is traditionally stimulated with heat (moxibustion) to help turn breech babies, and it’s grouped with the other “forbidden” pregnancy points due to its connection to uterine activity.
One more point worth knowing about isn’t on the foot at all: Large Intestine 4, the fleshy web between your thumb and index finger. If someone is giving you a hand and foot massage combo, this spot should be left alone. It’s considered one of the most potent points for inducing labor.
Why These Points Are Considered Risky
The concern centers on uterine contractions. In traditional Chinese medicine, these points are described as strongly moving energy and blood through the lower abdomen and reproductive organs. Modern research on Spleen 6 in particular suggests a plausible mechanism: stimulating this point may trigger oxytocin release and increase uterine blood flow, both of which play direct roles in labor contractions.
That said, the clinical evidence is limited. A systematic review in the journal Medical Acupuncture examined randomized controlled trials that used these “forbidden” points during pregnancy and found that no firm safety recommendations could be made due to the small number of studies. No adverse effects were documented in the trials reviewed, but the research is too thin to draw confident conclusions either way. Most practitioners take a “better safe than sorry” approach, which is reasonable when the stakes involve preterm labor or miscarriage.
The DVT Risk With Leg and Foot Massage
Beyond acupressure points, there’s a separate and more immediately dangerous concern: blood clots. Pregnancy significantly increases the risk of deep vein thrombosis (DVT), where clots form in the deep veins of the legs. These clots sometimes produce no obvious symptoms beyond mild swelling, which is easy to mistake for normal pregnancy edema.
A case report published in PubMed documented how leg massage in a pregnant woman with an unrecognized DVT dislodged a clot, causing a life-threatening pulmonary embolism. Deep tissue massage on the calves and lower legs can physically break a clot free and send it to the lungs. This is why many prenatal massage therapists use only light, gentle strokes on the lower legs and avoid deep pressure entirely. If one leg is noticeably more swollen than the other, feels warm to the touch, or is painful, skip the massage and get evaluated first.
First Trimester Considerations
Many prenatal massage therapists won’t work with clients until the second trimester. The first trimester carries a naturally higher risk of miscarriage, and while there’s no strong evidence that gentle massage causes miscarriage, therapists are cautious about liability and the increased blood flow that massage promotes. The American Pregnancy Association states that women can begin massage at any point during pregnancy, but you may find that individual therapists require a doctor’s note before the 13-week mark.
How to Massage Feet Safely During Pregnancy
Gentle foot massage during pregnancy isn’t just safe when done correctly. It’s beneficial. A randomized controlled trial involving 80 pregnant women found that 20 minutes of daily foot massage for five days significantly reduced lower leg swelling compared to standard prenatal care alone. The women who received massage had measurably smaller ankle, instep, and foot circumferences afterward.
The key is keeping the pressure light and the technique simple. According to guidelines from Allina Health, safe techniques include:
- Long, gentle strokes from the ankle down to the toes, always moving in one direction
- Small thumb circles on the sole of the foot, starting at the heel and working toward the base of the toes
- Gentle toe tugging and twisting using the pads of the fingers, never enough to cause pain
- Soft circular rotations of the heel and toes using both hands
The areas that are perfectly fine to massage include the top of the foot, the sole, and the toes. The spots to consciously avoid are concentrated around both ankle bones and the lower inner calf. Keep strokes slow and light in those transitional zones rather than applying sustained, deep pressure.
If you’re getting a professional prenatal massage, confirm that your therapist has specific training in prenatal techniques. A certified prenatal massage therapist will already know to avoid these points and will use appropriate pressure throughout. If you’re having your partner rub your feet at home, the simple rule is: stay on the foot itself, keep the pressure gentle, and avoid pressing firmly into the area around either ankle bone or the inner lower leg just above it.
