also the arch way at the back of my mouth looks very inflammed
White spots and inflammation are usually indicative of strep throat. You'll need to see a doctor and take antibiotics. You should be able to get in soon to the doc; they usually don't fool around with strep.
Yes, fairly. Not that your life is in danger, but you are highly contagious and it usually won't clear on its own. If left untreated it could turn into scarlet fever.
the little lump which is very near to my left tonsil, isn't white, its seems to be like a blister ( i think) but the back of my throat has like white spots on it, also my gums are going white around my teeth, i did have my wisdom teeth took out last year the back ones at the top, and i smoked afterwards, thats when i noticed the whiteness on my gums, but the white spots in the back of my throat i didn't really take much notice of them untill now...
Blisters, spots, and burning - sounds like an infection of some kind. Call the doctor.
didnt you recently post this exact same question? if you are still having problems, its past due time to see your dr.
