Hello doc! please help what are the cause of boils and best treatment ? thanks doc!

Where?: I see that you've been waiting for an answer for a while. Without much info, a "boil" cannot be named medically so it is impossible to answer. In fact, without seeing the patient with pertinent medical history, it is likely that no answers would be of much use for you. In the mouth, especially on gums, a "boil" often appears as a result of tooth infection. If it's in the mouth, see a dentist!

Boils are: Infection. Cause depends on where they are located and your medical history. See a doctor for a complete history ANS examination and treatment.
