I Have Runner’s Knee and Trail Running Makes My Knee Flare Up

Your knee may ache or flare up during trail running, especially on hills, uneven ground, or longer sections, because the repeated changes in footing and pace can keep stressing an already sensitive knee.

Trail running can make runner’s knee feel very different from running on a smooth, flat surface. You may start out feeling fine, then notice an ache around the front of your knee when the trail becomes rocky, uneven, steep, or downhill.

You may also notice that the discomfort builds gradually rather than appearing with one particular step. When your knee is already sensitive from repeated running, constantly adjusting to changes in the trail can keep bringing the pain back before your knee has had enough time to settle.

The Uneven Trail Makes Your Knee Flare Up

Your knee starts aching when every step feels slightly different.

You may feel fine on smooth sections but notice your knee become sore when you have to step around rocks, roots, ruts, or uneven patches. Those constant changes can make the knee feel less comfortable and cause the familiar runner’s knee ache to return during the run.

The Hills Bring The Knee Pain Back Later

Your knee may feel worse as the trail climbs and descends.

Uphill and downhill sections can make the front of your knee feel more pressured, especially after you have already been running for a while. You may notice the pain becoming more obvious near the end of the run or lingering when you stop, walk around, or take stairs afterward.

Why Your Knee Keeps Flaring Up

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.

Frequently Asked Questions

You may also find these commonly asked questions helpful.

Why does trail running make my runner’s knee flare up?

Uneven ground, hills, and repeated changes in footing can place more stress on your knee and bring runner’s knee symptoms back during a trail run.

Why does my knee hurt more on downhill sections?

Downhill running can make the front of your knee work harder, which may increase aching or pressure when your runner’s knee is already sensitive.

Why does my knee feel fine at first and then start hurting?

Your knee may tolerate the first part of the run but become more painful as repeated trail running adds up and the area becomes more irritated.

Can uneven trails make runner’s knee worse?

Yes. Constant changes in footing can make your knee adjust with nearly every step, which may increase symptoms when you already have runner’s knee.

Why does my knee still hurt after trail running?

Your knee may remain sore after the run because the repeated hills and uneven surfaces have continued stressing an area that was already having trouble recovering.
