Should I see a doctor again ?

So three days ago I got a TERRIBLE sore throat, it was the worst I’d ever had and I didn’t think it would go away for a while.

It surprisingly went away later that same night and was replaced with a very stuff nose that kept me up most of the night. I woke up in the morning feeling awful with a fever, and I threw up multiple after trying to drink water.

I went to the hospital and long story short I got some fluids and was sent home.

Yesterday I started to have a cough with my still existing runny nose, and today my really sore throat is BACK.

I never get sick like this, does it sound normal? No one else around me is sick either
