Thanks, guy, for the concern. ^_^
I seem to be feeling better. The cause of the problem was an infection in my gums resulting from a broken tooth that was never fixed (That is what I get for trying to crunch up a stale hard candy! A good lesson to stay away from the sweets)
I am on antibiotics now and, most likely, I'll have to have the broken tooth pulled because the break took off a good amount of the tooth.

Perhaps going to the dentist sooner would have taken care of it but dentist visits are so expensive.
