I want to you answer your questions and help you figure out what is happening. There is nothing that takes the place of a physical exam, but we will try.
1.)Do you have any other symptoms (fever, stiff neck, increase saliva, headache, other)?
2.)Any recent dental work?
3.)Is the swelling only on one side?
4.)I have just started this on-line diagnosis today. Always, a picture will help if possible.
Well lets start here.
