Pain that starts on the outside of your elbow and spreads into your forearm during tennis is often caused by an irritated tennis elbow tendon that becomes stressed with repeated gripping and racket swings.
Pain that begins around your tennis elbow and travels into your forearm during serves, backhands, or even gripping your racket is a common pattern when the tendon has been overworked. As the tendon becomes irritated, the muscles that attach to it can also become sore and tight, making the pain seem like it is spreading farther down your arm.
If your pain starts at the outside of your elbow but seems to run into your forearm while you play tennis, it can be unsettling. You might notice the ache becoming more noticeable as rallies get longer, when you hit several backhands in a row, or even when you carry your racket after the match.
This pattern is common with tennis elbow because the forearm muscles work constantly to grip the racket and control each stroke. When the tendon near the elbow has not fully recovered, those muscles often tighten and become sore too, making the discomfort feel like it extends well beyond the elbow itself.
The Ache Travels Farther As You Keep Playing
You may notice the pain starts near your elbow but gradually works its way into your forearm.
Early in a match the discomfort may stay in one small spot. As you continue hitting, gripping, and serving, your forearm muscles become more fatigued, making the aching or burning sensation spread farther down your arm.
Simple Everyday Gripping Starts Feeling Uncomfortable
You may notice the same forearm pain when opening jars, shaking hands, or lifting everyday objects.
Your forearm muscles are active during many daily tasks, not just tennis. If they are already irritated from repeated play, even light gripping can remind you that the area has not recovered and still needs time to heal.
Why The Pain Keeps Moving Down Your Arm
Your elbow 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 elbow feeling stiff, tight, weak, or painful during everyday movement and activity.
What Can Help Your Elbow Feel Better
Your elbow 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 same 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 tennis elbow really cause pain in my forearm?
Yes. The irritated tendon and the forearm muscles that attach to it often become sore together, making the pain seem like it travels down your arm.
Why does my forearm hurt more the longer I play tennis?
Repeated gripping and racket swings continue stressing the same area, so the pain often becomes more noticeable as your match or practice goes on.
Should forearm pain stop when my tennis elbow improves?
In many cases it does. As the tendon recovers and the forearm muscles are no longer overworked, the spreading pain usually settles as well.
Is it normal for gripping my racket to make the pain worse?
Yes. Firm gripping keeps the forearm muscles working, which can increase stress on the irritated tendon near the outside of your elbow.
When should I have spreading forearm pain evaluated?
If the pain becomes severe, you lose strength, develop numbness, or your symptoms continue to worsen despite rest, you should seek a professional evaluation.
