I Have Achilles Tendinitis and Speed Work Keeps Bringing the Pain Back

Achilles pain that returns during or after speed work can happen when repeated fast running stresses a tendon that has not fully recovered.

When you add speed work, you may notice your Achilles feels fine during easier running but starts hurting when you accelerate, run intervals, or push toward a faster pace. The pain may show up during the faster portion of the workout, or you may notice it more clearly afterward when the tendon becomes stiff and sore.

You may also find that the problem follows a frustrating pattern: the Achilles settles down when you reduce training, then the pain returns as soon as you bring speed work back. That can happen when faster running asks more from the tendon than it is currently ready to handle, especially when the increase in training comes faster than your recovery.

Pain Spikes When You Pick Up The Pace

Your Achilles may start hurting as soon as you accelerate into faster running.

You might feel a sudden pull, ache, or sharper pain at the back of your ankle when you move from an easy pace into an interval or hard effort. The faster pace places more demand on the Achilles, so a tendon that tolerates easy running may become painful when you ask it to work harder.

Your Achilles Feels Worse After The Speed Session

The pain may become more noticeable once the workout is over.

You may finish the session thinking your Achilles handled the workout, only to notice soreness or stiffness later that day or the next morning. If the tendon stays painful between workouts, starting another hard session before it settles down can keep bringing the same pain back.

Why Your Achilles Pain Keeps Returning With Speed Work

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 speed work bring my Achilles pain back?

Speed work places more stress on your Achilles tendon than easier running, so pain can return when the tendon has not fully recovered.

Why does my Achilles hurt when I run fast but not when I run easy?

Your Achilles may tolerate an easy pace but become painful when faster running increases the demand on the tendon.

Can Achilles pain show up after speed work instead of during it?

Yes. You may feel relatively comfortable during the workout and notice more soreness or stiffness later that day or the next morning.

Should I keep doing speed work if my Achilles pain keeps coming back?

If speed work repeatedly brings your Achilles pain back, reducing or stopping the activity that triggers the pain can give the tendon more time to recover.

Why does my Achilles pain improve when I reduce training?

Reducing training removes some of the repeated stress on your Achilles, which can allow the pain and stiffness to settle before faster running is added again.
