What should you know about metacarpophalangeal thumb middle joint pain?

The metacarpophalangeal joint is the knuckle where the thumb joins the hand. Pain may follow gripping, falls, repetitive work or a knock, and swelling or bruising can point towards a soft-tissue or bone injury. Stiffness after rest may occur with joint inflammation. Sudden severe pain with warmth and swelling can occur with gout. Widespread aches, fever or recent illness may suggest a condition affecting more than this joint, such as [Gout](/conditions/gout/) or [Fibromyalgia](/conditions/fibromyalgia/). A thumb that looks out of place, feels numb, or cannot move normally needs prompt assessment.

Reduce activities that trigger the pain while keeping the thumb gently moving within a comfortable range. For a recent injury, use a wrapped cold pack for short periods and keep the hand raised when swollen. Avoid forceful gripping and consider a temporary thumb support if it makes movement more comfortable; it should not be tight or worn continuously without advice. A pharmacist or clinician can help you choose pain relief safely, especially if you have stomach, kidney, liver or heart problems, take blood thinners, or are pregnant. Arrange an examination if symptoms persist, recur, or interfere with work or sleep.

Seek urgent care after a significant injury, visible deformity, rapidly increasing swelling, severe pain, loss of feeling, or a pale or blue thumb. Get same-day medical advice for a hot, red joint with fever or feeling unwell, because an infection needs prompt treatment. Book routine care for pain that does not settle, repeated episodes, morning stiffness, or reduced grip. Mention recent travel or illness if joint pain occurs with fever, as conditions such as [Dengue Fever](/conditions/dengue-fever/) can cause broader body aches.

Ask: Which structures might be causing the pain? Do I need an X-ray or another test? Should I use a splint, exercises or medication? What movements should I avoid, and when can I return to normal gripping?
