This could be caused by an infection (if there is an infection in your mouth, it may fill with fluid- blood or pus), or by a sore (if you have scratched the area or otherwise bothered it to the point of forming a sore in your mouth), or it could be a growth- which you should have checked.

Most likely, such a bump would be either a blister or cyst, or some sort of growth. The growth could be benign or might be malignant, so a dentist or oral surgeon should be consulted if the lump remains for two weeks or more.
