I Have Achilles Tendinitis and My Pain Gets Worse After Long Runs

Your Achilles may feel sore, tight, or increasingly painful after a long run because repeated push-off keeps stressing a tendon that has not fully recovered.

You may feel fine during the first part of a run, only to notice your Achilles becoming sore or tight as the miles add up. By the end of a longer run, the pain may be more noticeable with each step, and you may still feel it when walking afterward.

The longer you run, the more often your Achilles has to handle repeated push-off. If your tendon is already irritated or recovering from repeated strain, a long run can bring the pain back or make it noticeably worse. You may also notice stiffness when you first get up after the run, with the area taking time to loosen as you move around.

The Pain Builds As Your Long Run Goes On

Your Achilles starts feeling tighter or more painful as the miles add up.

You may begin your run with little or no pain, then notice soreness around the back of your ankle later in the run. The longer you continue, the more uncomfortable each push-off can become because the tendon is being stressed repeatedly without enough time to recover.

Your Achilles Stays Sore After You Finish

The pain can become more noticeable when you slow down, walk, or get up later.

After a long run, you may feel an ache, tenderness, or stiffness in your Achilles that was less noticeable while you were moving. You might also notice that your first few steps after sitting or resting feel especially tight before the area gradually loosens.

Why Your Achilles Pain Keeps Worsening After Long Runs

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

Why does my Achilles pain get worse after a long run?

Your Achilles may become more painful after a long run because repeated push-off continues stressing a tendon that has not fully recovered.

Why does my Achilles feel worse at the end of a long run?

Why does my Achilles hurt after running but feel better at first?

Your Achilles may feel better early in the run before repeated activity gradually brings the soreness or tightness back.

Why is my Achilles stiff after a long run?

Your Achilles may feel stiff afterward because repeated activity can leave the tendon sore and less comfortable when you stop moving.

Should I keep doing long runs if my Achilles pain keeps getting worse?

If your Achilles pain repeatedly worsens after long runs, reducing the activity that aggravates it and having persistent symptoms evaluated can help prevent the problem from continuing.
