We would have liked to know your age and if you have any other health problems as well. From your description of your problem and what you have been doing to your body through antibiotic abuse, we think you most probably have a fungal infection of your mouth and throat. If this is the case it has been caused by your irresponsible use of antibiotics. There are very good reasons you are advised to take such medicines on medical advice only and one of them is to prevent people from ending up in your state. Please go immediately to your nearest ENT for a physical examination and proper treatment- DO NOT TRY SELF MEDICATION. You can use the search doctors feature on our homepage to find one in your area if you are in Bengaluru.
