The plantar fascia is a thick band of tissue that runs along the sole of the foot from the heel to the toes. When it is overloaded, it becomes thickened and painful where it attaches to the heel bone. At LSRI, Dr Prashant Sankaye, Consultant MSK Radiologist, uses ultrasound to confirm the diagnosis and, when simpler measures have not helped, offers ultrasound-guided injection treatment.

Symptoms of plantar fasciitis

Pain under the heel, often sharp, with the first steps in the morning
Pain after resting that eases once you get moving, then returns after long periods on your feet
Tenderness on the inside of the heel

It is more common in runners, people who stand for long periods, people who are overweight, and those with tight calf muscles.

How we diagnose plantar fasciitis

The diagnosis is often clear from your symptoms and examination. Ultrasound confirms it by measuring how thickened the fascia is, and helps rule out other causes of heel pain such as a partial tear or a fat pad problem. MRI is occasionally used to look for a stress fracture of the heel bone or other causes when the picture is unclear.

What to expect at your appointment

Dr Sankaye reviews your symptoms and examines your foot.
The heel is scanned with ultrasound to confirm the diagnosis.
You discuss the options, including exercises and whether an injection is right for you.
If you go ahead, the injection is guided by ultrasound.
You receive aftercare advice, including how to return to walking and exercise.

Treatment options

Most people get better with simple measures, although it can take several months:

Calf and plantar fascia stretches, and strengthening exercises
Supportive footwear, cushioned heel pads or insoles
Reducing high-impact activity for a while, and managing weight where relevant

If pain persists despite these, injection treatments available at LSRI include:

Ultrasound-guided steroid injection: can reduce pain in the short term. Guidance helps place it accurately and reduces the risk of injecting into the heel fat pad.
PRP (platelet-rich plasma): an option for longer-standing cases. The evidence is still developing, and Dr Sankaye will talk through whether it suits you.
Botox (botulinum toxin): for stubborn heel pain, given into the tissues around the plantar fascia or into tight calf muscles. The evidence is still limited, and Dr Sankaye will talk through whether it suits you.

Questions about plantar fasciitis

How long does plantar fasciitis last?

Many cases settle within 6 to 12 months with stretching, footwear changes and activity changes. Treatment aims to ease pain and speed up recovery.

Is a heel spur the cause of my pain?

Not usually. Heel spurs are common on X-ray in people with no pain at all. The thickened, irritated fascia is usually the source.

How many injections will I need?

Often one is enough to settle pain so you can continue your exercises. Repeated steroid injections into the heel are avoided.

Can I keep running?

You may need to reduce your running for a while. Dr Sankaye can advise on a safe return based on your scan.
