When to worry about thumb pain with thumb arthritis

Thumb arthritis can make the joint at the base of the thumb sore during pinching, opening jars, turning keys, or prolonged hand use. A flare may settle with rest, but pain that keeps increasing or begins limiting ordinary tasks deserves review. New warmth and redness can reflect inflammation, while numbness or tingling may point to irritation of a nearby nerve rather than the arthritis alone. A fall, twist, or impact can cause a separate injury, especially when the thumb looks misshapen or feels unstable.

Reduce forceful pinching and gripping for a short period, while keeping the thumb gently moving within a comfortable range. Use a supportive thumb splint if a clinician has recommended one, and avoid wearing it so tightly that your fingers become numb, cold, or discoloured. Write down what triggers the pain, how long flares last, and whether swelling or weakness is changing. A clinician can examine the joint and discuss hand therapy, medicines, or other options suited to your health.

Arrange a routine appointment if pain persists despite reducing aggravating activities, repeatedly wakes you, or interferes with dressing, work, cooking, or grip. Seek prompt assessment after an injury if the thumb cannot move normally, appears crooked, becomes suddenly swollen, or you cannot hold objects. Obtain urgent help for a hot, very red, rapidly swollen joint with feeling unwell, or for new loss of sensation or colour in the thumb.

Ask whether the painful joint is the main source of symptoms, whether a splint or hand therapy could protect function, and which movements should be limited. Ask how to recognise an arthritis flare versus an injury or infection, and what plan to follow if pain suddenly worsens.
