Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. It is just a bite over the mole by simple bug. It will never cause any type of systemic infection that causes sore throat. Sore throat and cold is just coming of because of some different viral infection. So do not worry. You can take the drugs symptomatically. You can take the paracetamol, cetrizine, ranitidine this drug can cover the present viral infection. Please take the drug under doctors guidance. Over the bite mark your should maintian good cleanliness. You can do that with the good cleaning and dressing. Polysporin ointment application can be helpful. Please avoid injury to the part otherwise it will make the healing difficult. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
