I have a really sore mouth and throat which started after a day of severe vomiting (in excess of 20 times) even though my stomach was entirely empty. I also could not keep anything down including water.. I also had a slight fever and very strong headache and lower back pain. These symptoms eased after a day (nausea still remains slightly) but now I'm suffering whenever I try to talk or swallow and have noticed that there is a long swollen vein-like raised surface on the roof of my mouth. I have one on the other side but it is not nearly as sore or swollen. It's soft and when you press against it feels like a vein would but it's very painful. I feel like my entire mouth is sore and hurts and I have no idea if this is related to the severe viral symptoms I had yesterday. Could they be connected and should I still see a doctor even though vomiting has ceased? Thanks very much!
