Weakness, Blocked Nose and On/Off Fever since a month

Patient: I’m not feeling well since a month. Blocked Nose, Tired, weak fever on and off. Taking amxocillin 875 since 5 days now and even became a sore throat whilst taking it. I also use a lot nasal spray to get my nose free otherwise I can’t sleep. I will see the doctor after my second package Amoxicillin finishes. Do I have chronic Sinusitis?

Doctor:
