Need Nurse or Doctor's Opinion

The other night I did Molly and snorted adderall (I know stupid, and no this is not something I do often). I know when you do these things your mouth gets dry so you have 'to drink water. Guess I didn't drink enough because the next day my soft palate was a little red and mouth was dry and hurt to swallow, eat and drink... this was Sunday... now this is what it looked like yesterday (today it's not AS red but still) and the pain feels more like its starting down the right side of my throat. Throat isn't red though. It's a burning sensation and it hurts when I eat or drink ANYTHING
