I have no such diseases. I have some feet allergy since i was 9 or 10 months old. Nothing else. And I am 17 years old.
I will speak with someone tomorrow about this and let you know. Do you have any other diseases such as HIV, Tuberculosis, Syphillis etc? And do you have ANY other symptoms or problems? Any at all, even ones not in the mouth?
Is this types of patches are normal?? None of my relatives have this. So I am afraid. I once consulted a medicinal doctor, he said that there is no other symptom so there's no problem.
If it's been there since birth I doubt you are in grave danger? Have you been to the dentist before? If so, they surely would have noticed them and said something if they are out of the ordinary.
