Sick for a week, pain, nasal congestion, fatigue, out of breath?

I’ve been sick for a week and the symptoms are:
Pain all over my face (mostly around my temples.. makes talking and chewing difficult. It feels like muscle pain) nasal congestion, fatigue, out of breath a lot, chest infection? When I breath in or out it causes me to cough(some times wet sometimes dry). And dry mouth no matter how much water I am drink in.
