I have a huge dental abscess filling the whole of my right cheek from eye socket to chin. I went to the dentist yesterday and they cut the inside if my cheek over an over and squeezed blood out, it made very little difference to the size but did give me a black eye. They also gave me 2 different antibiotics which I am taking. I now feel ill, hot clammy, fatigue and a headache, should I be worried or is this notmal?
