<s>[INST] Last year I was treated for an gnat bite that was infected. I have been bittne again and ma having the same reaction....I am right in saying that last year I had Anti-boitics and steroids to cure this and stop the heat and widespread itch in surrounding areas, swelling too? [/INST] Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. This time your therapy remains the same. But the mode of delivery we have to change. This attributes to the allergic reaction you are going to receive. Every time you got bite reaction is severe and mode of treatment severity increases thereafter. As if you have taken prednisolone orally there is need of injectable therapy now. Please take antibiotic as you have taken previously. It will prevent further infection. Please maintain good hygiene by frequent washing and cleaning.  Chat Doctor. Avoid injury to the bite site otherwise infection will accentuate. I will be happy to answer your further concern on bit.ly/ </s>
