I have a series of white bumps on the front, left side edge of my tongue and the area feels very raw and hurts if I eat anything acidic.  I have had this occur before and they have cleared on their own but they seem to come up periodically.  Are they likely to be cankers or could they possibly be something more alarming like herpes or warts?
Hi, I have gone through your query. White bumps on tongue you have mentioned are most probably Authors Ulcers. There exact cause is unknown, but they are non-contagious, non-infectious and not sexually transmissible. These usually resolve on its own, but medicines can be taken for local application like Byte. Viscous lidocaine can be applied for pain relief. Good oral hygiene is also important to prevent secondary infection of the ulcers. Do consider positive feedback as a credit to my work. Let me know if you have any further questions. You can contact me on my page http
