Couldn't find what you looking for?


I have a bitter, sour taste in the back of my throat and now my tongue feels like it is blistered on each side.


Hi there,

Have you noticed any problems with your tonsils? If I am not mistaking you have problem with some sort of an infection in your mouth and your throat. The fact is that your blisters on side of your tongue are showing that you might have a viral infection The change in the taste can come from the infection on that spread to your taste glands. Have you been using any mouth wash after you brush your teeth? I know that this can be very helpful in preventing such infections to occur in first place. You can try to take some antibiotic medication to get rid of the infection and you have to watch what you eat in next few days.
