Sat Night I Had Not Eaten In 24-30 Hrs. Crazy

Sat night I had not eaten in 24-30 hrs. Crazy I know. I was on a trip and rushing around. No time to eat. Again stupid. Then I decided to do some drinking. I had lots of vodka and beer. I woke up the next day and threw up violently with lots of clear fluid the first time till I was dry heiving as violent as ever. Emediatly after my soft palate burned like crazy as well as pain and pressure. Now every time I eat any solid food it feels as tho its swelling and it hurts not as much as it feels irratated. Is this a cause from the vomiting? (I hadn't drank much water either) how can I stop this irratating swelling? It makes it a task to eat. And it ruins my appetite :(
