Plantar fasciitis and heel pain: causes, relief, and when to act

Plantar fasciitis is the most common cause of heel pain. The plantar fascia is a band of tissue that runs along the sole from the heel to the toes and helps support the arch. When it is overloaded it becomes irritated where it attaches to the heel, and that is where the pain is felt.

How to recognise it

The classic sign is a sharp pain under the heel with the first steps in the morning, or after sitting for a while. It often eases once you are moving, then returns after long periods on your feet. The heel is usually tender to press. It tends to come on gradually rather than from a single injury.

Why it happens

The fascia is overloaded when the demand on it outpaces what it can handle. Common contributors include a sudden increase in walking or running, long hours standing on hard floors, tight calf muscles, flat or high arches, and shoes with little support. Weight gain, or a change into flat and unsupportive shoes, can tip a foot over the edge.

Settling it down

Most cases improve with patience and consistent care. Easing the aggravating load for a while, rather than pushing through, gives the tissue a chance to calm. Calf and plantar fascia stretches, done regularly, are among the most effective measures. Supportive shoes and a cushioned, contoured footbed take tension off the heel. Custom-made orthotics can help where arch mechanics are part of the problem, by supporting the arch and spreading load away from the painful attachment. Simple steps such as rolling the sole on a cold bottle and returning to activity gradually round out the picture.

What to expect

Recovery is usually measured in weeks to a few months rather than days, and it is rarely a straight line. The most reliable results come from doing the simple things consistently: the daily stretches, the supportive footwear, and a sensible return to load. Where the foot mechanics are clearly part of the problem, orthotics can make the day to day more comfortable while the tissue settles. If progress stalls after a fair trial of these measures, it is worth reviewing the plan rather than pushing on regardless.

When to act

It is sensible to seek help when the pain has lasted more than a few weeks, when it is severe first thing in the morning, or when it is stopping you doing what you want to do. Early, consistent treatment tends to shorten the whole episode. An assessment can confirm that it is plantar fasciitis rather than another cause of heel pain, look at the mechanics of your foot and calf, and set a clear plan.

Heel pain that is caught early usually settles well. This is general guidance rather than a diagnosis, so if your heel has been troubling you, a consultation is the place to begin.
