Why is it worst first thing in the morning?
Because the fascia shortens and tightens overnight while the foot is relaxed, and the first steps stretch it abruptly. That pattern — severe for the first few minutes, easing as you walk, returning after sitting — is what identifies plantar fasciitis, and it is why stretching before you stand up makes such a difference.
What is the single most useful thing I can do?
Stretch before your feet touch the floor. Sit up in bed, pull your toes back towards you, hold for 30 seconds, three times — then put on supportive shoes before standing. Almost nobody is told to do it in that order, and it changes the morning pain more than anything else.
Is my heel spur causing this?
No. Heel spurs appear on X-rays of large numbers of people with entirely painless feet, and many people with severe plantar fasciitis have no spur at all. It is a consequence rather than a cause, nothing needs removing, and this is precisely why an X-ray is rarely useful here.
How long does it take?
Six to twelve months for most people — slow and genuinely frustrating, but the majority recover with stretching, footwear changes and managing load, without injections or surgery. Progress is not linear; flares after long days on your feet are normal.
Should I have an injection?
Not as a first step. Steroid injections relieve pain briefly but carry a real risk of rupturing the fascia or thinning the heel's fat pad — both of which cause worse and longer-lasting problems. Repeated injections should be avoided. Shockwave therapy is a better option for pain persisting beyond a year.
Can I keep running?
Usually, at reduced volume — complete rest is not necessary and not helpful. Cut back, swap some sessions for cycling or swimming, run on softer surfaces, and rebuild by about 10% a week. Pain that worsens the longer you run, rather than easing after the first minutes, is different and should be assessed for a stress fracture.
Do I need custom orthotics?
Rarely, at least initially. Inexpensive over-the-counter arch supports or heel cups work well for most people, and there is little evidence that custom devices do better as a first step. Save the expense until simpler measures have been given a proper trial.
Both my heels hurt. Does that matter?
It does, and it is worth mentioning specifically. Heel pain in both feet — particularly under 45, or with back pain, psoriasis or morning stiffness lasting over half an hour — can be an early sign of inflammatory arthritis rather than a mechanical problem. It is a recognised early feature of axial spondyloarthritis, and it frequently precedes the diagnosis by years.
