<s>[INST] I was stung twice yesterday,  I think by a wasp. Last night it was very itchy and red so I took antihistamine,  which didnt help. Today the area around the bites is very swollen, red and itchy,  spreading about 3-4".  I used hydrocortisone earlier but its still driving me mad. Ive just out Fucidin on - given by my doctor when going to Asia as I'm allergic to mosquito bites. Am I doing the right thing? [/INST] Hello,Usually wasp stings recover quickly and without complications.Mild to moderate reactions to wasp stings can be treated at home.-Wash the sting area with water and soap.-Place a cold pack to the wound to reduce swelling and pain.Keep the wound clean and dry.-Itching and skin irritation can be treated with hydrocortisone cream or calamine.Antihistamine drugs can reduce itching as well.-Over-the-counter pain relievers, such as ibuprofen, can be used for the pain due to wasp stings.Kind regards,Dr.Mersi </s>
