Common Causes of Heel Pain During Pregnancy

The most common causes of heel pain during pregnancy are added body weight, swelling from fluid retention, and hormone changes that loosen the ligaments in your feet. These changes flatten the arch, stretch the tissue along the bottom of the foot, and strain the heel bone, making sharp, stabbing pain with those first steps out of bed a frequent complaint for expectant mothers.

Heel pain in pregnancy is very treatable, and most relief options are simple, safe, and non-surgical. Below, we explain what’s happening in your feet, which conditions are most likely behind the ache, and when it’s time to seek professional care.

Understanding Heel Pain During Pregnancy

Your feet carry every pound you gain, every step you take, and every change your body makes over nine months. The heel – a small area of bone cushioned by a fat pad and anchored by thick bands of tissue – absorbs a surprising amount of that load. When the load changes faster than the tissue can adapt, pain shows up. As the belly grows, posture and gait change. Many women lean back slightly to compensate, so the heel takes more of the initial impact with each step.

• You gain weight over a short window. A typical pregnancy adds 25 to 35 pounds. Every pound multiplies across the foot when you walk – meaning the heel absorbs several times that in force with each stride.

• Ligaments become more elastic. Relaxin softens connective tissue throughout the body so the pelvis can widen for delivery. It doesn’t just target the pelvis – ligaments in the feet loosen too, letting the arch drop and the foot over-pronate.

Add long days on your feet, less comfortable footwear, and swollen ankles, and the heel becomes one of the most common complaint areas during pregnancy.

Common Causes of Heel Pain During Pregnancy

Let’s break down the three primary drivers in more detail.

Weight Gain and Increased Pressure

Weight gain is healthy and expected – but the foot doesn’t get a grace period to adjust. The plantar fascia, a thick band running from the heel bone (calcaneus) to the base of the toes, works like a bowstring holding up the arch. Extra weight increases tension on that band, particularly where it attaches to the heel.

The fat pad under the heel also compresses more with added load. When your natural shock absorber flattens under sustained pressure, the heel bone sits closer to hard surfaces, and every step on tile or concrete feels sharper.

Practical points:

• Hard flooring at home and at work multiplies the problem. Anti-fatigue mats in the kitchen or at a standing workstation make a real difference.

• Weight gain is usually fastest in the second and third trimesters – exactly when heel pain tends to appear or worsen.

• Barefoot walking around the house removes all cushioning at the worst possible time.

Swelling and Fluid Retention

Edema – fluid retention in the lower legs, ankles, and feet – affects most pregnancies to some degree. Blood and body fluid volume rises roughly 50%, and the growing uterus slows the return of blood from the legs.

Swelling raises pressure inside the foot’s soft tissues, making the plantar fascia and Achilles tendon feel tight and tender. It changes shoe fit. And it can compress the tibial nerve behind the inner ankle, producing burning or tingling that radiates into the heel and arch.

If you notice numbness or pins-and-needles along with heel pain, mention it at your visit. Nerve-related foot symptoms overlap with conditions like peripheral neuropathy and deserve a proper exam.

Ways to manage swelling:

• Elevate your feet above heart level for 15 to 20 minutes, two or three times a day.

• Move regularly – short walks or ankle circles every hour prevent pooling.

• Sleep on your left side when possible to reduce pressure on the vena cava.

• Stay hydrated. Counterintuitive, but dehydration makes the body hold onto more fluid.

• Have your shoe size rechecked. Many women go up a half or full size during pregnancy.

Hormonal Changes Affecting Ligaments

Relaxin and progesterone rise sharply in pregnancy. Relaxin loosens the tough bands that hold bones together. In the pelvis, that’s the point. In the feet, where 26 bones are held in position by dozens of ligaments, it’s a side effect.

Looser ligaments mean the arch has less passive support. The foot lengthens, flattens, and rolls inward – which is why some women’s feet permanently change size after pregnancy. The flattened arch stretches the plantar fascia further with every step, pulling on its attachment point at the heel.

Hormone levels stay elevated for several months after delivery, especially with breastfeeding. That’s why heel pain doesn’t always vanish the day the baby arrives – the ligaments need time to tighten, and the arch needs support while they do.

Plantar Fasciitis and Pregnancy

Plantar fasciitis is inflammation and micro-tearing of the plantar fascia where it anchors to the heel bone.

The tissue can’t remodel fast enough to match the new demand. Micro-tears accumulate at the heel attachment, the body sends inflammatory cells to repair them, and the area becomes tender and stiff.

Overnight, the fascia tightens while you’re off your feet. When you stand in the morning, that shortened tissue gets yanked back to full length in one motion – the classic first-step pain.

Symptoms of Plantar Fasciitis in Pregnant Women

Watch for:

• Sharp, stabbing heel pain with the first steps in the morning or after sitting for a while.

• Pain that eases after walking for a few minutes, then returns after long periods standing.

• Tenderness on the inside bottom of the heel when you press on it.

• A pulling or tight sensation along the arch, sometimes extending toward the toes.

• Pain that worsens late in the day rather than immediately after activity.

If pain is worse right at the start of exercise and improves as you warm up, plantar fasciitis is likely. If pain builds steadily with activity, something else may be going on.

Other Conditions That Cause Heel Pain in Pregnancy

Understanding the full list of causes helps you describe your symptoms more accurately at your appointment.

Achilles Tendinitis

The Achilles tendon connects the calf muscles to the back of the heel bone. Pregnancy-related weight gain and gait changes increase its workload, and looser ligaments elsewhere force it to work harder for stability.

Achilles tendinitis causes pain at the back of the heel rather than the bottom – with morning stiffness, tenderness when you squeeze the tendon, and flares after walking uphill or wearing flat shoes. Swelling or a thickened area along the tendon is common.

Heel Spurs

A heel spur is a calcium deposit that forms a bony protrusion on the underside of the heel bone, usually in response to long-standing tension from the plantar fascia. Many people have spurs and feel nothing – the spur itself is often not the pain source. But when surrounding tissue is already inflamed, a spur can add to the irritation.

An X-ray can confirm a spur, though treatment focuses on the soft-tissue inflammation causing the pain. Spurs take months to form, so one found during pregnancy likely predates it – a sign the foot has been under strain for a while.

Flat Feet and Fallen Arches

Because relaxin loosens the ligaments supporting the arch, many women develop temporary flat feet during pregnancy. Women who already had low arches often see them collapse further.

Signs include feet that feel wider, shoes that suddenly feel tight across the middle, and ankles that appear to roll inward when you stand. Fallen arches contribute directly to heel pain and can also cause arch aching, bunions, foot fatigue, shin discomfort, and knee or hip pain from changed alignment.

This is one of the clearest cases where arch support pays off – supporting the arch reduces the pull on the plantar fascia at the heel, treating the cause rather than the symptom.

Cracked Heels

Not all heel pain is deep. Dry, thickened skin around the heel rim can split into painful fissures, especially in winters with dry indoor heat. Pregnancy hormones affect skin hydration, and increased pressure on a widened heel pad pushes the skin outward until it cracks.

Cracked heels can bleed, sting with each step, and occasionally become infected. If you can’t comfortably reach your feet to inspect them in the third trimester, ask someone to check – or bring it up at your visit.

Home Care and Lifestyle Adjustments

Most pregnancy heel pain responds to conservative care. Start here:

• Supportive shoes, always. Choose a firm heel counter, cushioned sole, and real arch support. Avoid flat flip-flops and unsupportive slippers. Keep a supportive pair of house shoes by the bed.

• Stretch before your first step. Loop a towel around the ball of your foot and gently pull toward you, 30 seconds per foot. Then do a standing calf stretch against a wall – three sets, 30 seconds each.

• Roll the arch. Roll a chilled water bottle under the arch for 10 minutes in the evening to stretch and cool the tissue at once.

• Ice the heel. Fifteen to 20 minutes of ice on the tender spot, several times a day, reduces inflammation and numbs pain.

• Elevate and rest strategically. You don’t need bed rest – you need breaks. Sit and elevate every hour or two.

• Skip barefoot activity. No barefoot walking on tile, hardwood, or in the shower without a mat.

• Modify activity. Swap high-impact pounding for low-impact options like swimming or cycling.

• Ask before taking medication. Anti-inflammatories are generally discouraged in pregnancy, particularly in the third trimester. Clear any pain reliever with your obstetric provider first.

When to See a Podiatrist

Call our office if:

• Heel pain lasts longer than two weeks despite supportive shoes and stretching

• Pain is severe enough to change how you walk

• You have numbness, tingling, or burning in the foot

• Swelling is sudden, one-sided, or accompanied by redness and warmth

• You have visible cracks in the heel skin that are bleeding or not healing

• You have diabetes or a circulation condition

An exam typically includes watching how you walk, checking arch height standing and sitting, testing the Achilles tendon, and pinpointing exactly where the tenderness sits. Imaging is used only when it changes the plan.

Treatment for pregnancy-related heel pain centers on non-invasive options:

• Custom orthotics – prescription devices molded to your feet that support the arch relaxin has loosened, correct biomechanical imbalances, cushion the heel, and reduce pull on the plantar fascia.

• Taping, targeted stretching programs, footwear guidance, and night splints for day-to-day relief.

• Shockwave therapy for stubborn chronic heel pain – advanced options that accelerate healing and reduce inflammation at the cellular level. Timing for any treatment during pregnancy is always coordinated with your obstetric provider.

Because orthotics also help after delivery – when you’ll be carrying a baby and a car seat on feet that are still recovering – many patients find them worth getting during pregnancy rather than waiting.

Conclusion

The common causes of heel pain during pregnancy include added weight, fluid retention, and hormone-driven ligament looseness, which together flatten the arch and strain the heel. Supportive shoes, daily stretching, ice, and elevation resolve many cases at home. If pain persists past two weeks or interferes with walking, professional evaluation can help you move comfortably again.
