Sharp pain under the heel in the first few steps of the morning, easing after a few minutes of walking, returning after periods of sitting: that pattern is characteristic of plantar heel pain, often called plantar fasciitis. It is common, it is stubborn, and the intervention with the best evidence behind it is progressive loading of the calf and foot rather than the stretching and rolling most people do.
Expect months rather than weeks. Almost everyone recovers eventually, and almost everyone finds the timeline frustrating.
Why it happens
The plantar fascia is a thick band of tissue running along the sole from the heel to the toes, and it works as a spring during walking and running. Pain arises when the load on it exceeds what it currently tolerates, from a jump in activity, a change in footwear, more standing than usual, or a gradual increase in body weight.
The word "fasciitis" implies inflammation, and the tissue changes look more degenerative than inflammatory, which is part of why anti-inflammatory approaches disappoint people.
The morning pattern happens because the fascia shortens overnight and the first steps load it suddenly from a cold, shortened state.
What the evidence supports
Progressive calf and foot loading. The best-supported approach is heavy, slow calf raises done with the toes extended over a rolled towel, so the fascia is loaded through range. Slow tempo, high load, three times a week, progressing over months. This is the intervention with the strongest trial support and the one most people have never been told about.
Stretching, modestly. Calf and plantar fascia stretching helps with symptoms, particularly in the short term, but it is not the thing that resolves it.
Load management. Reducing the aggravating activity temporarily while building capacity. Not stopping entirely.
Footwear and orthoses. Supportive footwear helps some people and off-the-shelf insoles have modest support in the short term. Expensive custom orthotics do not clearly outperform cheap ones for this.
Not: rolling a ball under the foot as the main treatment. It feels good and eases symptoms briefly. It is not building anything.
The practice part
A yoga practice interacts with this in a specific way: a lot of it is done barefoot, and barefoot standing work on a hard floor is real load on an irritated fascia.
During the painful phase: reduce the barefoot standing time, work more from kneeling and seated positions, and consider practising in supportive trainers for standing sequences. This is a temporary adaptation and worth doing rather than pushing through.
The useful work: calf raises as above, toe and foot intrinsic work, ankle range, and hip and glute strength, because how you load the foot is determined further up the chain. Our feet and ankles piece covers the general version of this.
Balance work, once symptoms allow, which loads the foot in a useful way.
Things people try that do not do much
Ice, beyond brief symptom relief. Complete rest, which reduces capacity further. Steroid injections, which help in the short term and carry a small risk of fascia rupture, so they are a considered decision rather than a first step. And the arch supports bought at a chemist, used alone, without any loading work.
What is not plantar heel pain
Worth knowing, because the treatments differ. Pain at the back of the heel rather than underneath is more likely Achilles-related. Pain with pins and needles or numbness may be nerve-related. Heel pain following a specific traumatic moment, or that is severe and unremitting, needs assessment, stress fractures happen, particularly in runners and in people with low bone density.
Morning heel pain alongside stiffness in multiple joints lasting more than an hour is worth mentioning to a doctor, since inflammatory conditions can present this way.
Questions people ask
How long does plantar heel pain take to resolve?
Typically months, sometimes six to twelve. It resolves in the large majority of people. Consistency with loading work matters more than any single treatment.
Should I stretch or strengthen?
Both, with the emphasis on strengthening. Heavy slow calf raises with the toes extended have the best evidence. Stretching helps symptoms but does not build capacity.
Can I still practise yoga with heel pain?
Yes, with adaptations. Reduce prolonged barefoot standing on hard floors during the painful phase, use more kneeling and seated work, and add the loading exercises separately.
Are expensive orthotics worth it?
For this condition, custom orthotics have not been shown to outperform off-the-shelf insoles. Try a cheap supportive option alongside loading work before spending significantly.
