5 Signs of Plantar Fasciitis Most People Dismiss as a Bruised Heel

By Erica Coleman · August 16, 2026

You stepped out of bed and your heel hurt so badly you couldn’t put weight on it. By noon, it felt fine. You assumed you bruised it. Tomorrow morning, it’ll happen again.

Plantar fasciitis is the most common cause of heel pain in adults, affecting roughly 2 million Americans per year. The condition develops when the thick band of tissue running along the bottom of your foot becomes inflamed — and the pattern of pain is so specific that most people can identify it once they know what to look for.

The pain is worst with your first steps in the morning. This is the defining symptom. The plantar fascia tightens overnight, and your first steps stretch it before it’s warmed up, causing a sharp, stabbing pain in the heel. The pain usually eases within 10 to 15 minutes of walking as the tissue loosens. A bruised heel hurts consistently regardless of time of day. Plantar fasciitis follows a clock.

The pain returns after sitting for long periods. The same tightening that happens overnight occurs whenever you’re off your feet for an extended time. Standing up after sitting at your desk, getting out of a car, or rising from a couch produces the same sharp heel strike. If your heel hurts most during transitions from rest to movement, the fascia is the issue.

The pain is on the bottom of your heel — not the back. Plantar fasciitis pain concentrates on the underside of the heel, often slightly toward the front. Pain at the back of the heel suggests Achilles tendinitis, which is a different condition with different treatment. The location matters for diagnosis.

It gets worse after exercise — not during. Many people with plantar fasciitis feel fine while walking, running, or exercising, then experience intense heel pain afterward. The activity irritates the fascia, but the inflammation peaks during the rest period that follows. This delay confuses people who expect the pain to correlate with the activity itself.

It’s been getting gradually worse over weeks or months. Plantar fasciitis rarely appears suddenly from a single event. It builds over time — often starting as mild stiffness, progressing to noticeable pain, and eventually becoming severe enough to alter how you walk. Compensating by shifting weight off the affected heel can create secondary problems in the knee, hip, and lower back.

Treatment for most cases involves stretching, supportive footwear, ice, and over-the-counter anti-inflammatories. Night splints that hold the foot in a flexed position prevent the fascia from tightening overnight. Most cases resolve within 6 to 12 months with conservative treatment. But ignoring it doesn’t make it go away — it makes it chronic. If your heel has been hurting every morning for more than two weeks, the problem has a name and a treatment plan.
