An ankle sprain is the most common sports injury, and many people never get it properly treated. The result can be an ankle that keeps twisting. Whether it’s a recent injury or pain that won’t go away, the right diagnosis gets you back on your feet.

Common symptoms

Pain and swelling after twisting your ankle

An ankle that keeps giving way or twisting

Pain at the back of the heel or above it

Heel pain with your first steps in the morning

Difficulty walking or standing on your toes

Bruising or pain when pressing on the bone

What causes foot and ankle pain?

Ankle sprains

Stretched or torn ligaments after rolling the ankle, very common in football and basketball.

Chronic ankle instability

Repeated sprains that leave the ankle weak and loose. May need ligament repair.

Achilles tendinitis and rupture

From irritation of the tendon to a complete tear, often felt like a kick in the calf.

Ankle and foot fractures

Breaks after a fall, a twist or a direct blow that need prompt treatment.

Plantar fasciitis

Heel pain from irritated tissue under the foot, worse with the first steps of the day.

Ankle cartilage and impingement

Damage or bone spurs inside the joint that cause pain with activity.

How we diagnose and treat it

Dr. Zarur examines the stability of the ankle and the tendons and, when needed, orders X-rays, ultrasound or an MRI. A well-treated sprain today prevents an unstable ankle tomorrow.

Non-surgical

Rest, ice, a brace or walking boot, and physical therapy focused on balance and strength.

Immobilization

A boot or cast for some fractures and Achilles injuries.

Arthroscopy

Minimally invasive surgery for cartilage damage, impingement and loose bodies in the ankle. [Confirm Dr. Zarur performs it.]

Repair and fixation

Ligament reconstruction for chronic instability, Achilles repair or fracture fixation.

Foot and ankle pain: frequently asked questions

If you can’t put weight on the foot or the bone hurts when pressed, you need an X-ray. Only an exam and imaging can tell them apart.

Mild sprains improve in 1 to 3 weeks; severe sprains can take 6 weeks or more. Rehab with balance exercises helps prevent new sprains.

After a poorly healed sprain, ligaments can stay loose and balance gets worse. A specific rehab program, or sometimes surgery, can fix it.

Not always. Some ruptures are treated with a boot and rehab, while active patients often benefit from surgery. Dr. Zarur explains the options for your case.
