thanks. so these aren't typical of ARS?
Canker sores are small, shallow ulcers in the mouth that make eating and talking uncomfortable. Most are less than one-half inch in diameter, have a red rim and are covered by a yellowish-gray membrane. Occasionally, tiny ulcers group together or large, deep ulcers develop. Canker sores may occur on the tongue, soft palate, inside the cheeks or lips and at the base of the gums.
Canker sores differ from cold sores because they are not contagious, not caused by the herpes virus or other viruses, nor are they found on the outside of the lips or the exterior skin that surrounds the lips.
Mild canker sores (simple) are common, but the cause in many cases is unknown. In some cases, treatment is unnecessary. Pain usually decreases after several days and the sores heal within one to three weeks. Occasionally, severe (complex) canker sores develop that are larger than one centimeter in diameter and/or last longer than two weeks. Severe canker sores may indicate other medical problems.
Most canker sores are resolved with over-the-counter treatments or self-management techniques, such as practicing good oral hygiene and avoiding nuts and spicy or acidic foods. When canker sores persist, recur frequently, are accompanied by a fever or are unusually large or painful, they may warrant treatment by a specialist
Highly, overwhelmingly unlikely. Might be some other STD though. Or could be cold sores or something.
Go see doctor and get professional opinion.
Take care.
