white spots on my throat

well, white spot to be exact. the only other time i've noticed white spots on my throat i had strep. however, now i only have a minor sore throat, and it seems to only be sore in one specific spot, not where the spot is. i don't have access to any type of reputable medical facility, but can get antibiotics. i pretty much need to make the call as to whether or not to take antibiotics. anyone ever get white spots with a minor sore throat?
