I Have Knee Pain When I Run and My Knee Feels Like It’s Grinding

Knee pain that feels like grinding when you run can happen when repeated running stresses an irritated or roughened area of the knee, making each stride feel painful or uncomfortable.

When your knee hurts and seems to grind during a run, you may notice it most clearly when your knee repeatedly bends and straightens with each stride. The sensation does not necessarily mean that something is literally grinding bone against bone; irritation around the kneecap, cartilage changes, or other problems inside the knee can all contribute to a rough or grinding sensation during movement.

Running gives your knee very little time between one stride and the next, so an already irritated area has to keep working repeatedly. If the patellofemoral joint or other structures inside the knee are irritated, the repeated bending and straightening can make the movement feel less smooth and more painful as you continue.

The Repeated Bending Of Running Can Make Grinding More Noticeable

Every stride repeatedly bends and straightens your knee, which can make an irritated area feel rough or painful.

As you run, your knee moves through the same basic motion over and over, especially as you land, bend the knee, and push into the next stride. If the kneecap or tissues within the joint are irritated, that repeated motion can make the grinding sensation more noticeable than it is when you are simply walking around.

The Grinding Feeling Can Increase As Your Run Goes On

Repeated strides can make knee irritation more noticeable as your muscles and joint become fatigued.

At the beginning of a run, your knee may feel relatively comfortable, only for the grinding sensation and pain to become more obvious several minutes later. As your legs fatigue, it can become harder to keep the movement comfortable, and the irritated knee may become increasingly painful with continued repetition.

Why Your Knee Keeps Grinding During Runs

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 my knee hurt and feel like it is grinding when I run?

Running repeatedly bends and straightens your knee, which can make irritation around or inside the joint feel painful or rough with each stride.

Does a grinding feeling in my knee mean my knee is damaged?

Not necessarily. A grinding sensation can have several causes, so persistent or painful grinding should be evaluated rather than assumed to mean a specific type of damage.

Why does my knee start grinding more as I run?

Repeated running can increase irritation and fatigue around the knee, making the grinding sensation more noticeable as the activity continues.

Should I keep running when my knee hurts and feels like it is grinding?

If running consistently causes pain and grinding, reducing or stopping the activity until the cause is understood can help prevent further aggravation.

When should I have knee grinding checked?

Have persistent, severe, or worsening knee pain or grinding evaluated, especially if you also have swelling, locking, instability, or difficulty bearing weight.
