[|AI|]  Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. The possible swelling is because of the other infection or may be because of the allergic reaction to the sting. I advise you should take the cetirizine for the allergic reaction, diclofenac and serratopeptidase for pain control and healing enhancer, ciprofloxacin tablet for infection control. Please take the above medication under your doctors' guidance. Local application of the antibiotic ointment can help, you can use polypoid ointment. Please maintain good local hygiene. This is equally helped full in treating infection as do antibiotics. Avoid excessive sweating, wear cotton undergarments. I will be happy to answer your further concern on bit.ly/ Chat Doctor. Thank you, ChatDoctorInfectious diseases specialist, ChatDoctor.
