Things to consider that i did not mention:

my 13 month old son recently has begun attending daycare. his first center was attended at 10 months of age. he recently started at his second place.

he's brought home MANY common childhood viruses.

secondly is that after 2 or 3 weeks of the chronic sore throat, i got a terrible sinus problem. i still have post-nasal drip and possibly a slight bronchitis.

finally, there is the issue of a cavity in my back two molars on the top left side of my mouth. when having them filled, my nerve was so inflamed that it blocked all anesthesia and the dentist was unable to finish the proceedure.

don't know if any of that may help make sense of what i am experiencing, but thanks.
