What should you know about left hand swelling at night?

During rest, the hand may stay in one position for a long time, and a bent wrist or dependent arm can make puffiness more noticeable when you wake. Local inflammation after overuse, a minor injury, or a wrist problem can also cause swelling. Distal Radius Fracture presents after an impact or fall and may cause wrist pain, swelling, tenderness, and difficulty using the hand. Rheumatoid Arthritis presents with inflammatory joint symptoms that may include swelling and stiffness, often affecting more than one joint. A pattern limited to one hand still deserves attention when it is new or unexplained.

Remove rings before sleep if they feel tight, and support the forearm so the hand is comfortably elevated rather than compressed. Gently open and close the fingers if this is painless. Review recent gripping, lifting, travel, bites, injections, or wrist injuries, and note whether swelling improves by morning. Do not tightly wrap the hand or apply heat when the cause is uncertain. If there is an injury, protect the area and arrange an examination.

Get urgent help if swelling appears suddenly with chest discomfort, breathlessness, faintness, or new weakness. Seek prompt care for severe pain, fever, redness that is spreading, pus, a cold or blue hand, marked tenderness, deformity, or inability to move the fingers. Arrange a clinical review when swelling keeps returning, lasts through the day, or comes with morning stiffness, numbness, or several painful joints. See Hand Swelling for related signs and more detail on Distal Radius Fracture and Rheumatoid Arthritis.

Ask whether the pattern suggests a joint, tendon, circulation, or nerve issue. Mention the time of onset and any injury or new activity, then ask whether you need imaging, blood tests, or a short period of observation and what changes should bring you back sooner.
