Yeah i'm doing well now, i got to know the other day that apart from celiac i have even egg an milk sensitivities which can't be discovered with allergy-tests, so the cure is on full throttle and well on its way! Thanks for asking.
But back to your case, the bloatings, they haven't been there before the Antibiotics and when this all started?
Facial swelling often relates to allergies/sensitivities, swelling of the tissue or/and areal infections caused by allergy.
I don't know what the facial sweat may be caused by, maybe toxins.
I'm alittle concerned that you didn't mention runny nose that comes often in pair with sensitivities although allergies doesn't necessarily have to be sensitivities.
It would be best for me not to theorize too much since it might stir up too much of the facts that may come out when you appoint a doctor, but your suspicion of milk is a strong indication.
Lactose intolerance/Diabetes type 2 i come to think of.
