Hi there, If it is not actually painful, and you are not unwell, it is unlikely to be strep throat. Are the white spots on the tonsils, the tissue that are on either side of the throat? If so, it could be tonsillar stones, which are basically buildup of food debris and salivary material within the gaps and crypts of the tonsils. It works on a similar mechanism as tartar buildup on your teeth. What you are feeling is when one of these stones get dislodged and goes to your throat, which is then harmlessly swallowed. They are simply a nuisance and not dangerous at all. Some people find that it increases the frequency that they do get sore throats, but that doesn t seem to be the case in you. The other problem is that sometimes it can cause bad breath, but if that doesn t bother you, I would recommend just leaving them be. Even if you do manage to get them out, they will reaccumulate in no time. The only definite option is to remove the tonsils, which is pretty drastic for such a trivial problem. Hope this helps, and let us know if you have further questions. Regards, Dr. Teh Editted to add: Just occured to me to give you other possibilities if the spots are not actually in the tonsils. If they are on the wall right at the back of the throat and you still feel fairly well, it could be candidiasis, or thrush of the throat. This is less common in healthy people but can be considered due to your age and diabetes background. This can be treated with a nystatin suspension, which is gargled and swirled around the mouth, then swallowed. Oral antifungals will also work if you can get your hands on the suspension. If it does start to get more persistent and sore or you get unwell, then it could have progressed to a strep throat, and only then should you consider the oral antibiotics like amoxicillin and such. Hope this helps you better. Regards, Dr. Teh
