What should you know about hand redness and swelling?

Redness may be limited to a pressure point, a bruised area, a finger joint, or a larger part of the hand. Swelling after impact or overuse can accompany soft-tissue irritation. A hot, tender, expanding area can need prompt evaluation for infection or a deeper inflammatory problem. Stiff, swollen knuckles affecting several joints may occur with Rheumatoid Arthritis. A wrist injury, including a Distal Radius Fracture, can also cause swelling and colour changes around the hand. These possibilities overlap, so the pattern and examination matter more than colour alone.

Take off rings and bracelets, rest the hand, and keep it elevated when practical. Do not squeeze, puncture, or apply irritating creams to red skin. If a minor knock caused the symptoms, use a cool pack wrapped in cloth for short periods and avoid placing it directly on the skin. Marking the edge of spreading redness can help you notice change, but it should not delay medical care. Seek advice if redness persists, swelling returns, or hand movement becomes limited.

Get urgent care if redness spreads quickly, the hand is very hot or painful, fever or chills develop, pus appears, or you feel unwell. Emergency assessment is needed for severe swelling with numbness, colour change, cold fingers, deformity, or loss of movement. A bite, puncture, wound, or recent procedure lowers the threshold for prompt review.

When did the redness begin, and does its shape or warmth suggest infection? Should I use cooling or keep the hand still? What symptoms would mean I need same-day reassessment?
