Plantar fasciitis usually lasts MONTHS, not weeks. The good news: about 8 in 10 people are better within a year, most of them without surgery or injections.
The classic sign is sharp pain under the heel with your first steps in the morning, or when you stand up after sitting. It eases as you walk around, then aches again by the end of a long day on your feet.
What helps most is simple and boring: stretch the arch, strengthen the calf and foot, and wear shoes that support you. Done daily, for weeks. Nothing works fast, so give each step time before you judge it.
What’s going on in your heel
The plantar fascia is a thick band of tissue that runs from your heel bone to the base of your toes. It holds up your arch. When it’s loaded more than it can handle, the attachment at the heel becomes irritated and thickened.
- Common triggers: a jump in walking or running, a new job on hard floors, weight gain, tight calves, or worn-out, flat shoes
- The heel spur myth: many people with a spur on X-ray have no pain, and many with pain have no spur. The spur is rarely the cause
- Why mornings hurt: the fascia tightens overnight, and the first steps stretch it suddenly
What actually helps
- Arch stretch before your first step: sit on the edge of the bed, cross the sore foot over your knee, and pull your toes back toward your shin until you feel a stretch in the arch. Hold 10 seconds, 10 times. This stretch has done better in trials than calf stretching alone
- Calf stretch: hands on a wall, sore leg back, heel down, knee straight, then bent. 30 seconds each, a few times a day
- Heel raises on a step: stand on a stair with a rolled towel under your toes, rise up slowly on both feet, and lower slowly over three seconds. Build to the sore leg alone. Strength helps the fascia cope with load
- Supportive shoes: cushioned heel, firm arch, no flat slippers or barefoot on hard floors while it’s sore. Put shoes on before you get out of bed if you can
- Insoles: off-the-shelf arch supports or heel cups work about as well as expensive custom ones. They ease pain in the short term more reliably than the long term
- Cut back, don’t stop: swap some running or long standing for cycling or swimming while it settles
- Roll the arch: a frozen water bottle under the foot for a few minutes eases pain after a long day
Heel pain gets better with daily boring work, not one big fix.
Night splints, shockwave and other extras
- Night splints: they hold the foot pulled up while you sleep so the fascia doesn’t tighten overnight. The evidence is mixed. Some people find the mornings much easier, others can’t sleep in them
- Shockwave therapy: sound waves aimed at the heel. It is a reasonable next step when several months of exercise and good shoes haven’t worked. It’s not a first treatment
- Weight: if you’re carrying extra weight, losing some takes load off the heel with every step
- Surgery: rarely needed, and only after many months of proper treatment have failed
A word of caution on cortisone
A cortisone shot into the heel can ease pain quickly, but the relief often fades within weeks to a few months. It doesn’t fix the reason the fascia got overloaded.
- Rupture risk: repeated injections can weaken the fascia. In people who have several shots, roughly 1 in 40 go on to tear it
- Fat pad thinning: cortisone can thin the natural cushion under your heel, which can leave the heel sore in a new way
- If you have one, use the pain-free window to get the stretching and strengthening going. That’s what lasts
See cortisone shot side effects for the full picture.
How long each stage takes
- Weeks 1 to 6: daily stretches, better shoes, less load. Mornings often start to ease first
- Weeks 6 to 12: strength work builds. Pain drops, with bad days after long walks or busy shifts
- Months 3 to 12: most heels settle in this window. Keep the exercises going a few times a week even once it’s gone
If the pain is at the back of the heel rather than underneath, it’s more likely the Achilles tendon. See Achilles tendinitis. If it’s under the ball of the foot instead, see metatarsalgia.
Get seen today if
- You felt a pop in the arch followed by sudden pain, bruising or swelling. The fascia may have torn
- The heel is red, hot and swollen, or you have a fever
- You can’t put weight on the foot
Get it checked if
- Pain is worse at night or at rest, not with first steps
- You have numbness, tingling or burning in the heel or sole. A trapped nerve can mimic plantar fasciitis
- Both heels hurt, with stiff joints or back pain, especially if you’re young. Some forms of arthritis start in the heel
- Pain started after a big jump in running and hurts when you squeeze the sides of the heel bone. It could be a stress fracture
- Nothing has improved after two to three months of daily stretching, strengthening and good shoes
Plantar fasciitis is slow to arrive and slow to leave, and most heels do leave it behind.
