Achilles tendonitis causing pain and stiffness at the back of the heel

Achilles tendonitis is irritation and inflammation of the large tendon connecting your calf to your heel. It causes pain and stiffness at the back of the heel or ankle — often worst in the morning or after activity — and it tends to worsen if you keep pushing through it.

At Premier Lower Limb Clinic in Jersey City, Dr. Ibrahim Elkattawy diagnoses the cause of your heel-cord pain and treats it before it becomes a chronic problem or a tendon tear.

Symptoms

  • Pain and stiffness along the back of the heel, worst in the morning
  • Pain that increases with activity, running, or climbing stairs
  • Tenderness or thickening of the tendon
  • Swelling that doesn’t ease with rest

What Causes It

Achilles tendonitis is usually an overuse injury — a sudden increase in activity, tight calf muscles, worn or unsupportive shoes, or repetitive stress. Flat feet and other mechanical issues can add strain to the tendon. Without treatment, ongoing irritation can weaken the tendon and raise the risk of a rupture.

Many patients with Achilles pain also experience heel pain or have underlying biomechanical issues that contribute to tendon stress.

Treatment Options

  • Activity modification and a structured return-to-activity plan
  • Stretching and eccentric strengthening of the calf and tendon
  • Heel lifts, bracing, or immobilization to offload the tendon
  • Custom orthotics to correct contributing mechanics
  • Advanced options for stubborn or chronic cases

We also treat a wide range of foot and ankle sports injuries affecting athletes and active individuals.

Frequently Asked Questions

Should I keep exercising through Achilles pain?

No — pushing through tends to make it worse and can lead to a tear. It’s better to get evaluated and follow a structured plan.

Why is it worse in the morning?

The tendon stiffens overnight, so the first steps in the morning are often the most painful. This is a classic sign of Achilles tendonitis.

How long does it take to heal?

Mild cases improve in a few weeks with the right care, while chronic cases take longer. Early treatment shortens recovery.

Can Achilles tendonitis become serious?

Yes. Ongoing irritation weakens the tendon and increases the risk of a rupture, which is why timely treatment matters.

Will I need surgery?

Most cases resolve without surgery. It’s reserved for severe, chronic, or ruptured tendons that don’t respond to conservative care.

Do you accept insurance?

Yes, we accept most major insurance plans and will check your coverage.
