What Causes Achilles Tendon Pain?

Feeling tight and sore in the back of your ankles? Maybe even some burning pain? Chances are, your Achilles tendon is to blame. 

Your Achilles tendon is the thick band of tissue that connects your calf muscles to your heel bone. It plays a major role in just about every movement you make with your feet, from walking and running to jumping and climbing stairs.

Because you use it constantly, it’s also one of the most commonly irritated tendons in the body. 

Fortunately, Achilles tendon pain isn’t usually a mystery. In many cases, there’s an underlying cause that Dr. Maurice Aiken and our expert podiatric team at Bay Breeze Foot & Ankle Specialists in Dunedin, Florida, can treat before the problem becomes more serious. 

Here’s a closer look at the most common causes. 

1. Overuse injuries

At the top of the list are overuse injuries. When you repeatedly stress the tendon without giving it enough time to recover, tiny tears develop in the tissue. Over time, that microscopic irritation builds up, leading to inflammation and pain — a condition we call Achilles tendonitis. 

You’re most at risk for an overuse injury when you:

• Suddenly increase the intensity of your workouts
• Start working out more frequently
• Add hills or sprinting to your routine
• Jump back into exercise too quickly after a break

The bottom line is, your Achilles tendon (and the rest of your musculoskeletal system) needs time to adapt to increased activity. When you push that progression too fast, painful damage usually follows. 

2. Tight calf muscles

Tight calves and Achilles pain tend to go hand in hand. A stiff calf muscle places additional strain on the tendon when you exercise or walk. That constant pulling irritates the tendon over time, and movements feel uncomfortable, especially first thing in the morning. 

3. Wearing the wrong shoes

Your footwear matters much more than you might realize.

Shoes that lack proper support or cushioning can increase strain on your Achilles tendon, particularly during exercise. Worn-out athletic shoes are a common culprit because they don’t absorb shock effectively.

On the flip side, suddenly switching to completely flat shoes or spending a lot of time barefoot can also aggravate the tendon if your body isn’t used to it.

4. Flat feet and mechanical problems

The way your feet move affects the entire chain of your legs and ankles.

If you have flat feet or abnormal walking mechanics, you’re placing uneven stress on the Achilles tendon. Eventually, that extra strain can lead to irritation and inflammation.

In some cases, custom orthotics or supportive footwear can help improve alignment and reduce stress on the tendon.

5. Your age 

As we get older, tendons all over our bodies naturally lose some flexibility and blood supply, making them more vulnerable to injury and slower to heal. 

Your Achilles tendon is no exception, and it’s one of the main reasons why Achilles tendon pain becomes more common in adults in their 30s, 40s, and beyond — especially in weekend warriors who stay active but may not stretch, recover, or condition consistently.

Treating Achilles tendon pain

The first step is to figure out where your Achilles tendon pain came from. Once we nail down a cause, Dr. Aiken and our team get to work creating a rehabilitation and treatment action plan. 

Mild soreness after activity typically improves with rest, stretching, and supportive shoes. But if the pain keeps coming back, worsens, or starts limiting your activity, it’s time to get it evaluated.

Depending on the severity of the damage, your plan may include stretching, physical therapy, orthotics, regenerative medicine, activity modifications, or other therapies to help you heal safely.

Remember: Ignoring Achilles tendon pain can increase your risk of more serious injuries, including a tendon rupture, which may require surgery and a lengthy recovery.
