Achilles Tendonitis: Why Your Heel Still Hurts (And How to Fix It Fast Without Making It Worse)

You’ve tried resting, stretching, and maybe even icing for weeks, but your Achilles still hurts. If that sounds familiar, you might be putting effort in the wrong place. As the team podiatrist of the Phoenix Suns, Dr. Ryan Golub has seen many cases of Achilles tendon pain go from manageable to severe without proper treatment. Here’s how you can avoid that:

What Achilles tendonitis actually is (and why it lingers)

Most people assume Achilles tendonitis is just inflammation that will go away with rest. That’s only half the story.

Acute Achilles tendonitis is inflammation of the tendon, usually from a sudden spike in activity, tight calves, or poor footwear. If you catch it early and treat it correctly, it can be resolved in a few weeks.

But if that pain in the back of your heel has been hanging around for a couple of months, you’re likely dealing with tendinosis, which is a different condition entirely. Tendinosis means the tendon has started to degenerate at a cellular level. Rest alone won’t fix this because the tendon needs controlled loading to heal.

This distinction is important because the Achilles tendonitis treatment for each is different. Many people who are stuck in a cycle of pain are treating tendinosis like it’s tendonitis.

The biggest mistakes that keep you in pain

Here are the common mistakes that aggravate your condition:

• Overstretching: When your Achilles hurts, your instinct is to stretch it out. But aggressive stretching can actually compress an already irritated tendon against the heel bone, which makes things worse.
• Ignoring early warning signs: A stiff Achilles in the morning that warms up after a few minutes isn’t normal. That’s the tendon telling you it’s under stress. Most people push through this stage and don’t seek help until the pain becomes constant.
• Wearing flat, unsupportive shoes at home: You might have great running shoes, but spend eight hours a day barefoot or in flip-flops on hard tile. In Arizona’s climate, where sandals and bare feet are the default for most of the year, this is one of the most common contributors we see.
• Returning to activity too soon: The pain fades, you go for a run, and it comes right back. If you want to know how to heal Achilles tendonitis fast, the answer starts with not rushing your recovery.

How to treat Achilles tendonitis the right way

If you’re in the acute phase (pain started within the last few weeks), rest and ice can help reduce inflammation. But if the pain has persisted beyond that window, you need to start loading the tendon, not resting it.

Eccentric heel drops are the gold standard among Achilles tendonitis exercises. Stand on the edge of a step, rise up on both feet, then slowly lower on the affected side only. This controlled loading stimulates the tendon to rebuild stronger collagen. 

Footwear matters too. A shoe with a slight heel raise takes pressure off the Achilles. Custom orthotics can correct alignment issues that contribute to tendon overload, especially if you have flat feet or overpronation.

When it’s more serious than you think

If you feel a sharp pop, notice a visible gap or significant swelling in the tendon, or can’t push off when you walk, you may be dealing with a partial tear. This isn’t something to manage at home.

You should also see a podiatrist for Achilles tendonitis if your pain hasn’t improved after six to eight weeks of consistent home treatment. Advanced options like pulse wave therapy, physical therapy, or in rare cases surgery can address damage that conservative treatment can’t reach.

How to prevent it from coming back

Prevention comes down to two things: don’t spike your activity too fast, and keep your calves and ankles strong year-round.

Warm up before every workout. A five-minute walk before you run costs you nothing and protects the tendon from cold-start stress. When you’re increasing mileage or intensity, follow the 10% rule: don’t add more than 10% per week.

Invest in long-term ankle strength. Calf raises, eccentric heel drops, and single-leg balance work should be part of your routine.

Don’t let it become a long-term problem
