Why Does My Knee Hurt After Taking Time Off From Tennis?

If your knee starts hurting when you return to tennis after taking time off, you may notice soreness building as you move around the court, even though your knee felt fine during the break.

If your knee hurts when you start playing tennis again, the break may have left you less prepared for the demands of a full session. Your quadriceps, which help control your knee as you bend and straighten your leg, may tire sooner than before, while the patellar tendon below your kneecap can become sore when you repeatedly push off, land, or change direction. Even if you were pain-free while resting, returning to your previous level of play can bring those symptoms back.

Taking time off can allow existing soreness to settle without necessarily resolving the problem that caused it. If your knee was already sensitive before the break, the first sessions back may reveal that it still struggles with the demands of tennis. A sudden increase in activity can also leave the joint temporarily swollen or stiff, making bending and straightening your knee less comfortable.

Your Knee Hurts When You Start Moving Around The Court Again

Your knee may struggle with the sudden return to quick bending, pushing off, and changing direction.

During tennis, your knee repeatedly bends to lower your body, straightens as you push toward the ball, and helps you stop when you reach it. After time away, your leg muscles may not be as prepared for these quick movements, placing more demand on the kneecap area and patellar tendon. This can make your knee ache during lunges, feel sore when you push off, or hurt when you plant your foot to change direction.

Repeated Rallies Make Knee Pain Build As You Play

As your legs tire, the same court movements can become harder for your knee to tolerate.

Early in a session, your knee may feel manageable, but repeated rallies can leave your quadriceps tired and less able to control each landing and change of direction comfortably. You may then notice pain becoming more pronounced when reaching for a wide shot or getting low for a ball. If you keep playing through increasing pain, the repeated demands can aggravate an already sensitive tendon or knee joint rather than allowing the symptoms to settle.

Why Your Knee Keeps Hurting After Returning To Tennis

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 after taking time off from tennis?

Your knee may hurt because it is not yet accustomed to the repeated lunges, stops, turns, and push-offs required when you return to tennis. An existing knee problem may also become noticeable again when you resume playing.

Should I play tennis if my knee hurts after a break?

Reduce or pause play if your knee pain increases during a session. Return gradually when everyday movement is comfortable, and seek medical advice if the pain persists or worsens.

Why does my knee hurt more as I play tennis?

Your knee may become more painful as your leg muscles tire and repeated court movements place increasing demands on a sensitive knee joint or tendon.

How do I return to tennis without making my knee hurt?

Start with shorter, easier sessions and gradually increase playing time and intensity. Allow your knee to settle between sessions rather than immediately returning to your previous workload.

When should I get knee pain checked after returning to tennis?

Seek medical evaluation if your pain persists, worsens, or repeatedly returns. Get prompt care for a severely swollen knee, inability to bear weight, locking, or a knee that gives way.
