Plantar heel pain.
Not every heel is the same.
Plantar fasciitis is common, but heel pain can also come from the fat pad, calcaneus, nerve entrapment, tendon disease, or referred pain. Persistent symptoms deserve a diagnosis before another generic treatment is added.
The plantar fascia is only one source of heel pain
History and examination help distinguish classic plantar fascia pain from calcaneal stress injury, fat-pad pain, Baxter nerve entrapment, tarsal tunnel, Achilles-related pain, and referred symptoms.
Ultrasound can assess plantar fascia thickness, echotexture, focal tearing, calcification, perifascial fluid, and adjacent structures. It can also help determine whether the imaging finding matches the painful location.
Footwear, calf capacity, and plantar loading matter
Progressive loading
Calf and foot strengthening can help restore capacity instead of relying only on stretching and rest.
Footwear & surface
Changes in shoes, work demands, running volume, body weight, or standing exposure can alter plantar load.
Ankle mechanics
Restricted ankle dorsiflexion and calf stiffness may contribute in some patients and should be addressed when relevant.
A heel spur is not the diagnosis.
Calcaneal spurs are common and may be incidental. Treatment should focus on the symptomatic tissue and the forces acting on it.
The target and the tissue matter
Persistent plantar fascia disease can sometimes lead to discussion of PRP or other image-guided procedures. Steroid can reduce symptoms in selected cases but is used thoughtfully around the plantar fascia because repeated or poorly targeted exposure can create tissue risk.

What patients usually want to know.
Can ultrasound confirm plantar fasciitis?
Ultrasound can show plantar fascia thickening, altered echogenicity, focal defects, calcification, and surrounding changes. The findings should be matched to the location and pattern of pain.
Does a heel spur cause plantar fasciitis?
Not necessarily. Heel spurs are common and can be present in people without pain. They are one imaging finding, not the diagnosis by themselves.
Can PRP be used for plantar fasciitis?
PRP may be considered for selected chronic plantar fascia disorders after diagnosis, rehabilitation, and other options are reviewed. Evidence and expected benefit should be discussed in the context of the individual case.
What else can mimic plantar fasciitis?
Calcaneal stress injury, heel fat-pad pain, nerve entrapment, Achilles-related conditions, inflammatory disease, and referred pain can all produce plantar heel symptoms.
