L.S.
Hi L.,
Sounds exactly what ran through my family, too. Our daughter got sick Christmas and has had that same post-nasal drip for a few weeks now, this even after a round of antibiotics (the cold turned into an ear infection). Hubby and I eventually got it and we're dealing w/ the post-nasal drip going on two weeks now. Lots of throat-clearing in our house over the last month or so! :)
