A few days ago I threw up several times within a few hours for no apparent reason. My mouth was burned, swollen, painful to chew or swallow. It healed almost completely yesterday except for two spots on the roof of my mouth at the back left. This morning I woke up and the swellings were throbbing, my teeth feel like they ve moved. there is a new larger and more painful swelling at the root of my shifting tooth. I m not exactly looking for a diagnosis but; Should I take an antihistamine for the resulting sinus pressure? Should I consult a dentist or a physician? Ruling out abcesses, what else shows up like this and should i be worried about malignancy? Thank you for your time!Amanda
