Swollen Hand After an Insect Bite: What to Do

Local swelling, warmth, redness, and itching can be the skin's response to an insect bite. The hand may swell more because dependent tissue allows fluid to collect. A spreading red area, increasing warmth, pus, worsening pain, or fever can suggest infection rather than a simple local reaction. Swelling after an unnoticed injury can have another explanation, including a fracture. Ongoing swelling in both hands or repeated morning stiffness points away from one bite and may need assessment for an inflammatory condition such as rheumatoid arthritis.

[Hand Swelling](/symptoms/hand-swelling/) provides broader information about this symptom.

If a stinger is visible, gently scrape it away with a flat edge rather than squeezing the venom sac. Wash the area with soap and water, remove rings before swelling increases, and use a cool pack wrapped in cloth for short periods. Keep the hand raised when practical. Do not scratch, lance, or apply unknown household substances. A pharmacist or clinician can advise whether an antihistamine or other treatment is suitable for your symptoms and medical history.

Call emergency services for trouble breathing, throat or tongue swelling, faintness, widespread hives, or rapidly worsening symptoms after a bite. Seek same-day care for swelling that spreads quickly, severe pain, fever, pus, red streaks, or difficulty moving the fingers. Get assessed after a bite if the hand becomes unusually cold or discoloured, or if swelling followed a significant injury; a [Distal Radius Fracture](/conditions/distal-radius-fracture/) can also cause hand swelling.

Ask: Does this look like a local reaction or infection? Was a stinger removed fully? Which medicine is safe with my health conditions? How long should swelling take to improve? Could recurrent swelling or stiffness indicate [Rheumatoid Arthritis](/conditions/rheumatoid-arthritis/) rather than the bite?
