I caught a cold on Saturday. It seemed to be on it s last legs by Tuesday night. Wednesday afternoon my throat was feeling increasing worse so I went to the doctor and they said it was just a viral infection, I assume a sore throat . Now it s 1am on Thursday my top lip is swollen (started from right, but has moved over to right side), my tongue is swelling (started from left side) and I m salivating excessively. The saliva is hard to swallow because of my throat.
