I Have Runner’s Knee and Treadmill Running Makes My Knee Hurt

Your runner’s knee may start hurting once you begin treadmill running because the steady, repeated motion keeps your knee bending and straightening without much change in pace or movement.

If your knee feels fine when you are walking around but starts hurting once you get into a steady treadmill run, the change in activity can explain why you notice it there. Runner’s knee commonly involves pain around or behind the kneecap, and the repeated motion of running can make that area increasingly uncomfortable when it is already sensitive.

Your kneecap moves as your knee bends and straightens with every stride, while your quadriceps and hip muscles help control your leg. On a treadmill, that pattern continues at a fairly consistent rhythm, so your knee keeps repeating the same movement instead of getting much of a break from the activity.

The Steady Treadmill Stride Keeps Your Knee Moving

A constant running rhythm gives your knee very little variation in movement.

Once you settle into your treadmill pace, your knee continues bending and straightening with each stride. If the patellofemoral area is already irritated, that uninterrupted repetition can make the pain show up during the run even if the first few minutes feel manageable.

The Pain Becomes More Noticeable As You Keep Running

As your legs tire, the same treadmill pace can become harder for your knee to tolerate.

Your hip and thigh muscles have to keep working throughout the run to control your leg and support each stride. As they become fatigued, the knee may start feeling less comfortable, and a mild ache that was easy to ignore at first can become more obvious as you continue.

Why Your Knee Hurts During Treadmill Running

Your knee 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 knee feeling stiff, tight, weak, or painful during everyday movement and activity.

What Can Help Your Knee Feel Better

Your knee 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.
