I woke up with a swollen, red hard palate. It feels rough at the back like I may have burnt it or something but I don t remember damaging it, more that I just woke up like that. I did have a dental check up the day before, just a check up and clean and polish. The dentist said everything was fine and good at the time and there was no swelling in the palate then. It developed the next morning, I wonder if it s related or just a coincidence, Today there is some yellow pus forming at the back of the hard palate. My glands may be a little swollen too and I do feel extra tired, though I am 35 weeks pregnant. Any ideas?
