Im Just Getting Over The Flu And Still Have A

Im just getting over the flu and still have a stuffy/runny nose and a pretty bad cough. But today it felt like my face had been punched in. And now the roof of my mouth is very painful and full of pressure. I ate ice cream earlier and it seemed to help for a short amount of time. However I looked at the roof of my mouth through a picture and there is a red vain coming from my back tooth up almost to the middle of the roof of my mouth. It is thin, but concerned me and i dont know if it has to do with the pain. My cheek bones hurt and my chin, and i also have a headache. Hope i described everything properly for you.
