<s>[INST] hello doc, last week i started to notice some itching in my outer lips and it started to form little bumps, like an allergy. the problem is that this allergy is lasting too long, and its a little swollen, what could it be? it itches a lot, but there are no other symptoms, thanks [/INST] Cellophane You for contacting Chat Doctor. This could be allergic response may be due to insect bite or dust. I would suggest you following things:> Don't touch that area with dirty hands.> Apply poly fax plus ointment over it twice a day> Wash hands before and after applying ointment> take cetirizine one at night for 4 days. It will reduce itch Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. Wishing you good health. </s>
