Infectious Diseases




For the past two months I have had a string of continuous canker sores on my tongue. They are small, red bumps with white on top. I only have about one to two at a time, but I am wondering why and if this could be of any significance. Thanks!


Canker sores are a mysterious illness. Despite many attempts to link them to an infectious agent, nothing has turned up. Often, they emerge during stressful times, but otherwise, the cause is unknown. There is little to do but treat them symptomatically.
