Pain at the start of your run often happens because your Achilles tendon is stiff after resting, making the first few minutes uncomfortable until it gradually loosens with movement.
Pain at the start of your run is a common pattern with Achilles tendinitis because the tendon is stiff before it has warmed up. You may feel a pulling or aching sensation during the first few minutes, and while it often improves as you keep running, that does not necessarily mean the tendon has fully recovered.
You might lace up feeling perfectly fine, only to notice the back of your heel tighten within the first few strides. Every push-off feels a little uncomfortable, and you may even change your stride without realizing it. Then, after several minutes, the pain fades enough that running starts to feel normal again.
This happens because the Achilles tendon has been resting before your run. If it is already irritated from repeated training, those first powerful push-offs place stress on a tendon that has not loosened yet. As your body warms up, the tendon becomes more flexible, which is why the pain often eases instead of continuing to build immediately.
The First Few Minutes Feel Like The Toughest Part
Your Achilles feels stiff before it settles into a rhythm.
You may notice the tendon feels tight, sore, or as if it needs a few minutes to "wake up." That early stiffness often improves once the tendon has been moving consistently, even though the underlying irritation is still present.
The Pain Often Comes Back After The Run Ends
Feeling better during the run does not always mean the tendon has recovered.
You might finish your run feeling encouraged, only to notice the Achilles tightening again after you cool down or later that evening. That pattern suggests the tendon is still being stressed faster than it can fully recover between runs.
Why Your Achilles Tendon Could Be Taking Longer To Heal
Your Achilles tendon 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 tendon feeling stiff, tight, weak, or painful during everyday movement and activity.
What Can Help Your Achilles Tendon Feel Better
Your Achilles tendon 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 same 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.
Is it normal for Achilles tendinitis to hurt only at the start of a run?
Yes. Early-run pain that eases as you warm up is one of the most common symptom patterns of Achilles tendinitis.
Why does my Achilles feel better after a mile?
As the tendon warms up and becomes more flexible, it often tolerates movement better, making the pain less noticeable.
Should I keep running if the pain goes away?
If the pain repeatedly returns during or after your runs, reducing training and addressing the cause is usually better than simply running through it.
Why is my Achilles sore again after I finish running?
The tendon can tighten again as it cools down, especially if it was already irritated before your run began.
Can warming up help reduce Achilles pain?
Yes. A gradual warm-up often reduces early stiffness, although persistent pain still deserves attention to prevent the problem from worsening.
