When everyday tasks start to ache

You try to open a jar, lift the kettle or turn a door handle, and a sharp or burning ache shoots along your forearm. Or perhaps it builds slowly through a day of typing, painting, lifting boxes or playing an instrument until your arm feels heavy and tired. The forearm is involved in almost everything you do with your hands, so when it hurts, you notice it constantly.

The forearm runs from the elbow to the wrist. It contains two bones, the radius and ulna, and many muscles and tendons that bend and straighten the wrist and fingers and rotate the hand. Three major nerves also pass through it on their way to the hand. Pain can come from any of these structures, or be referred from the neck or elbow.

Patterns worth knowing

• Overuse and muscle strain: an aching, tired or tight forearm after repeated gripping, lifting, typing or a new activity. Often improves with rest.
• Tennis elbow (lateral elbow pain): pain on the outer side of the elbow that can spread down the back of the forearm, worse with gripping or lifting with the palm facing down.
• Golfer's elbow (medial elbow pain): similar, but on the inner side of the elbow and forearm, often worse with gripping and bending the wrist.
• Tendon irritation near the wrist: pain, swelling and sometimes a creaking feeling on the thumb side of the forearm, often after repetitive wrist movements.
• Nerve compression: tingling, numbness or burning rather than simple aching. Carpal tunnel syndrome affects the thumb side of the hand; cubital tunnel syndrome, from pressure on the ulnar nerve at the elbow, affects the ring and little fingers. A pinched nerve in the neck can also send pain and tingling down the arm.
• Injury: a fall onto an outstretched hand can sprain the wrist or fracture one of the forearm bones, causing swelling, bruising and pain with movement.
• Arthritis in the wrist or elbow joints can cause pain that spreads into the forearm.

Less commonly, forearm pain can be linked to a blood clot in the arm, an infection, or pain spreading from the heart. Those causes come with specific warning signs, listed below.

Easing an overworked forearm

• Relative rest. Cut back on the movements that hurt most, rather than stopping all use. Complete immobilization usually isn't needed for overuse pain.
• Change your grip. Lift with your palm facing up where possible, use both hands, and choose tools with thicker, padded handles so you don't have to squeeze as hard.
• Cold or warmth. A wrapped cold pack for 10 to 15 minutes can calm a flare after activity. Warmth can relax tight muscles. Always keep a cloth between pack and skin.
• Gentle stretches. Slowly stretching the wrist forward and back with the elbow straight, holding for a few breaths, helps some people. Stop if it causes sharp pain or tingling.
• Check your setup. At a desk, keep wrists straight and forearms supported. Take short breaks every 30 minutes or so.
• Return gradually. When pain settles, build back up slowly. Strengthening exercises guided by a physical therapist are a common part of recovery from tendon problems.

Some people find a forearm strap or brace helpful for tennis or golfer's elbow; a physical therapist can advise whether one suits you and how to wear it. A pharmacist can talk you through pain relief options that fit your health.

What an assessment may involve

A clinician will ask what you do with your arms at work and at home, when the pain started and what makes it worse. They will check where it is tender, test grip strength and movement, and look at feeling and reflexes in the hand. Depending on what they find, they may suggest X-rays after an injury, an ultrasound for tendons, or nerve tests if numbness is a feature. Many people are referred to a physical or occupational therapist for exercises and practical advice.

Living with a forearm that flares

For people whose jobs or hobbies rely on their hands, such as typists, mechanics, hairdressers, musicians, climbers and parents carrying small children, forearm pain can feel like a threat to daily life. Pacing helps: spread demanding tasks across the day, rotate between different activities, and warm up before long sessions. Many people also find it useful to hear how others have adapted their tools, workstations and routines.

The bottom line

Forearm pain is most often caused by overuse, tendon strain such as tennis or golfer's elbow, or nerve compression. Easing the strain, adjusting your grip, using cold or warmth, gentle stretching and a gradual return to activity help many people. Get emergency help for arm pain with chest symptoms or stroke signs, and urgent care after an injury with deformity, severe swelling or color change.
