Can I Run With A Swollen Knee?

A swollen knee can feel tight, full, or painful when you run, and continuing to run can aggravate the irritation causing the swelling.

If your knee is swollen when you try to run, you may notice that it feels different from ordinary post-run soreness. The knee may feel tight when you bend it, uncomfortable when you land, or restricted when you try to pick up your pace. Swelling can occur when the knee has been irritated by repeated activity, a recent strain, or an injury, and running gives the area very little opportunity to rest between steps.

Swelling can also change how comfortably your knee moves. Extra fluid and irritation around the joint can make bending and straightening feel less natural, while pain may cause you to unconsciously alter how you run. That combination can place additional stress on the knee and surrounding muscles as you continue your workout.

Each Running Step Keeps Loading Your Swollen Knee

Running repeatedly bends and straightens the knee while your body absorbs impact with every step.

When your knee is already swollen, that repeated motion can be uncomfortable because the joint has less room to move freely. The quadriceps, hamstrings, patellar tendon, and other tissues around the knee also have to keep working as you land, push off, and bend the leg, which can make an irritated knee hurt more during a run.

The Swelling Becomes More Noticeable As You Keep Running

Repeated running can make an already irritated knee feel increasingly full and restricted.

You may start your run feeling reasonably comfortable and then notice the knee becoming tighter or more painful several minutes later. As the activity continues, repeated bending and impact can increase irritation around the knee, making the swelling more noticeable and making each step feel less comfortable.

Why Your Knee Keeps Swelling During 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.

Frequently Asked Questions

You may also find these commonly asked questions helpful.

Can I run with a swollen knee?

It is generally better to avoid running if your knee is swollen and painful, because repeated impact can aggravate the underlying problem.

Why does my knee swell when I run?

Running repeatedly stresses the knee, and swelling can develop when the joint or surrounding tissues become irritated by that repeated activity or by an underlying injury.

Should I stop running if my knee swells?

If running causes your knee to swell or makes existing swelling worse, stop the activity and allow the cause of the swelling to be evaluated.

Can running make a swollen knee worse?

Yes. Continued running can increase irritation and make swelling, stiffness, or pain more noticeable when the knee is already aggravated.

When should I get a swollen knee checked?

Seek professional evaluation if your knee swelling is severe, follows a significant injury, prevents normal movement, or persists or worsens.
