I Have Achilles Tendinitis and Running Makes My Achilles Feel Less Flexible

Your Achilles feels less flexible when you run because repeated push-off can make an irritated tendon tight and harder to move comfortably.

When your Achilles feels less flexible during a run, you may notice that your ankle does not move as freely as it normally does. The first few steps may feel restricted, or the tightness may become more obvious when you increase your pace or keep running for longer.

Achilles tendinitis can leave the tendon less comfortable with repeated stretching and movement. When your calf and Achilles have to keep working through each stride, that reduced flexibility can make your ankle movement feel limited and less natural during the run.

The First Few Steps Feel Tight Through Your Achilles

An irritated Achilles tendon may not stretch as comfortably when your foot moves through each stride.

As you run, your ankle repeatedly moves as your heel rises and your foot pushes you forward. If your Achilles is already irritated, that repeated movement can make the tendon feel tight rather than allowing your ankle to move freely.

Your Achilles Gets Tighter As The Run Continues

Repeated strides can make restricted movement more noticeable as your calf and Achilles fatigue.

You may begin running with only a slight sense of tightness, then notice your Achilles feels increasingly restricted as you continue. As the calf and tendon keep working without a break, the movement can start to feel less fluid and your normal stride may become harder to maintain comfortably.

Why Your Achilles Feels Less Flexible

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 feel less flexible when I run?

Your Achilles may feel less flexible because repeated running can make an already irritated tendon tight and restrict comfortable ankle movement.

Why does my Achilles get tighter while running?

Repeated strides keep your calf and Achilles working, which can make tightness more noticeable as the run continues.

Can Achilles tendinitis reduce flexibility?

Yes. Achilles tendinitis can make the tendon and ankle feel stiff or restricted, especially during repeated activity such as running.

Why does my Achilles feel stiff at the beginning of a run?

Your Achilles may feel stiff at the start because the irritated tendon may not move as freely when you first begin running.

Should I keep running if my Achilles feels less flexible?

If your Achilles becomes increasingly restricted or painful while running, reducing or stopping the activity can help prevent further aggravation.
