Why Does My Achilles Hurt When I Run?

Achilles pain when you run can show up as a sharp, sore, or pulling feeling with each stride, especially during push-off, when repeated strain stresses the tendon.

If your Achilles starts hurting during a run, the problem is often connected to the repeated work the tendon has to handle with every step. Your calf muscles and Achilles tendon work together to help you push your body forward, so running repeatedly asks the same area to work without much variation.

When the Achilles is already irritated or strained, that repeated demand can make normal movement harder. The tendon may become less flexible and more sensitive to the repeated push-off required during running, particularly when you increase mileage, pace, hills, or training frequency.

Push-Off Keeps Putting Stress On Your Achilles

Each stride asks your Achilles tendon to help drive your foot away from the ground.

As you push off during running, your calf muscles tighten and the Achilles tendon transfers that force toward your heel. If the tendon is already irritated or fatigued, repeatedly going through this motion can make the painful part of your stride more noticeable and harder to ignore.

The Pain Becomes More Noticeable As You Keep Running

Repeated strides can make an already stressed Achilles work harder as your run continues.

As the miles add up, your calf and Achilles continue repeating the same movement thousands of times. Fatigue can make the area less comfortable with each stride, so you may start with manageable soreness and find that the pain becomes more obvious later in the run or immediately afterward.

Why Your Achilles Keeps Hurting When You Run

Your Achilles has a hard time healing when blood flow and circulation are limited.

Tendons, ligaments, and other soft tissues naturally receive less blood supply than many other parts of the body. Because of this, they often take longer to heal after repeated stress or injury, leaving you more vulnerable to lingering pain and a cycle of reinjury.

When circulation through the area remains limited, injured tissues have a harder time receiving the vital oxygen and nutrients they need to repair and heal. This can leave your Achilles feeling stiff, tight, weak, or painful during everyday movement and activity.

What Can Help Your Achilles Feel Better

Your Achilles starts feeling better when blood flow and circulation improve.

Chinese herbs have been used for centuries to promote healthy blood flow and circulation. Their medicinal properties help break up stagnant blood and fluids that remain trapped around injured tissues, interfering with circulation. As circulation improves, blood flows more freely through the area, allowing those tissues to receive the oxygen and nutrients they need to heal properly.

Topical herbal remedies made with these Chinese herbs can help relieve pain while improving blood flow and circulation to injured tissues. The right product depends on your symptoms and whether you're in the acute or chronic stage of recovery.

If you have pain, swelling, inflammation, or bruising, Acute Sinew Liniment helps relieve these symptoms by increasing circulation and dispersing stagnant blood and fluids around the injured area to speed recovery. During the acute stage of healing, getting circulation moving early allows injured tissues to receive the fresh blood, oxygen, and nutrients they need to repair and heal.

If your injured area is especially swollen, red, or warm to the touch after a recent injury or flare-up, Sinew Herbal Ice is also used to reduce swelling and inflammation while restoring normal circulation so you can quickly regain range of motion. While traditional ice is commonly used to reduce swelling, Sinew Herbal Ice acts as an ice alternative to reduce swelling and inflammation while also dispersing accumulated blood and fluids to speed the healing process.

If you no longer have swelling or inflammation, but still have pain, stiffness, weakness, or sensitivity in cold and damp weather, Chronic Sinew Liniment helps relieve these symptoms by strongly stimulating circulation and increasing blood supply to injured tendons and ligaments to promote their healing. This is especially important because tendons and ligaments naturally receive less blood supply, which is why chronic injuries can take longer to heal.

If you have residual pain and stiffness, or the area becomes more painful in cold weather, Sinew Injury Poultice is also used to significantly stimulate circulation to injured tendons and ligaments to further promote their healing. By strongly increasing circulation, it counteracts the reduced blood flow caused by cold weather that commonly aggravates chronic tendon and ligament injuries.

If you exercise, play sports, or do other strenuous activities, Sinew Sports Massage Oil warms and stimulates muscles for exertion and relieves muscle tightness and soreness after activity. Warming and preparing your muscles before activity can improve flexibility, enhance performance, and reduce the risk of injury.

Frequently Asked Questions

You may also find these commonly asked questions helpful.

Why does my Achilles hurt when I run?

Achilles pain when running is often caused by repeated stress on the tendon during push-off, especially when the area is already irritated or fatigued.

Why does my Achilles hurt more as I run?

Your Achilles may become more painful as you run because repeated strides continue stressing the tendon while your calf and lower leg become fatigued.

Why does my Achilles hurt during push-off?

Push-off places repeated demand on the Achilles tendon, so an irritated or strained tendon may become painful each time you drive your foot away from the ground.

Should I keep running if my Achilles hurts?

If running consistently causes Achilles pain, reducing or stopping the activity and allowing the area to settle can help prevent the problem from becoming worse.

Can Achilles pain from running keep coming back?

Yes. Achilles pain can keep returning when repeated running continues to stress a tendon that has not fully recovered from earlier strain.
