Swollen Forearm Near the Wrist Without Pain

Notice whether the swelling is on one side, soft or firm, mobile or fixed, and whether it changes with arm position or activity. A recent knock, repetitive gripping, a tight watch or bandage, or an injection can cause local swelling. Tendon problems around the elbow or forearm can sometimes occur with little pain early on; see the pages on Tennis Elbow and Golfer's Elbow for related patterns. A lump that enlarges, becomes hard, changes the skin, or remains unexplained deserves a clinical examination.

Remove constricting jewellery or clothing and keep the arm gently moving if movement is comfortable. Rest from repetitive lifting and keep the hand supported when sitting. Do not puncture, squeeze, or repeatedly press the swelling. Take a photo beside a familiar object and note when it appears, whether it changes during the day, and any new numbness, colour change, weakness, or pain. Arrange a routine appointment if it persists or returns.

Seek urgent assessment if swelling develops quickly, the forearm becomes tight, the hand is cold or discoloured, or you develop numbness, weakness, severe pain, breathlessness, or chest pain. Prompt care is also appropriate for fever, spreading redness, warmth, drainage, or swelling after an injury.

Ask what examination is needed, whether a tendon or joint problem fits the location, and which activities or supports to avoid while the swelling is being assessed.
