Why Stretching Beats Cortisone for Heel Pain

Plantar fasciitis is one of the most common reasons people see a podiatrist, and one of the most frustrating to treat. Most patients want the fastest fix, which has often meant a cortisone injection. New research suggests a slower, simpler approach may deliver better results over time.

What the Latest Research Found

A recent prospective study followed 100 patients with plantar fasciitis and split them into two groups. One received a single corticosteroid injection. The other followed a structured stretching program paired with anti-inflammatory medication, contrast baths, and a shoe insole. Researchers tracked pain and function across 16 weeks.

The pattern was clear. In the first few weeks, the injection group felt better faster. By the 12- and 16-week marks, the stretching group had pulled ahead with better pain scores and improved function. The authors concluded that structured stretching provides more durable relief and belongs at the front of the treatment plan.

These results come from a 2025 clinical trial and reinforce guidance podiatrists have shared for years.

Why Stretching Works Better Long Term

The name is a little misleading. Plantar fasciitis is not primarily an inflammation problem. It is a tissue overload problem. The plantar fascia, the thick band of tissue running from the heel to the toes, gets overstressed and develops small tears. Pain follows that ongoing damage.

A cortisone shot calms symptoms. It does not correct the mechanical strain underneath. Stretching does. Lengthening tight tissue, strengthening the supporting muscles, and giving the fascia room to recover addresses the actual cause.

Stretches Worth Doing Every Day

Consistency matters more than intensity. The protocol used in the study was daily and structured. A few of the most useful movements:

• Plantar fascia stretch. Cross the affected foot over the opposite knee, pull the toes back toward the shin, and hold for 30 seconds. Do this before standing in the morning.
• Calf stretch. Face a wall, place one foot back with the heel down and knee straight, and lean forward until the upper calf stretches.
• Soleus stretch. Same position, but bend the back knee slightly to reach the lower calf.
• Frozen bottle roll. Roll the arch over a frozen water bottle for several minutes to combine stretching with cold therapy.

These work best done daily for at least six to eight weeks before you judge the results.

Support Beyond Stretching

Stretching rarely works alone. Most patients recover faster with a few supportive additions: a quality arch-supporting insole, a night splint that holds the foot in a gentle stretch during sleep, and comfortable shoes worn consistently throughout the day. Small, steady habits tend to outperform any single aggressive treatment.

If you are dealing with plantar fasciitis in Westwood, these conservative steps are almost always the right starting point.

When to See a Podiatrist

Some cases need more than home care. If you have stayed consistent with stretching, insoles, and good shoes and pain still limits your day, a professional evaluation is warranted. Options such as shockwave therapy, light therapy, and platelet-rich plasma injections carry strong evidence for stubborn cases. Cortisone still has a role, used carefully rather than as a first move. Surgery is a true last resort, and most cases resolve without it.

At SoCal Sports Podiatry, we build treatment plans around what the evidence supports and what fits your daily life.

If heel pain is shaping how you move or keeping you up at night, schedule an evaluation with a Westwood, CA Plantar Fasciitis doctor to find the right next step toward lasting relief.
