Feeling heavy head with little giddiness

Sir/madam. I  drenched in rain for 10 min and the same day night i felt with full chill and shivering. The next day mrng there was no chill and shivering but still not feeling fully well. Very little bit of heat in body and little sickness. I started to take  the paracetamol ip 500 mg and after that new problem arises that is I  feel some weight in head and little bit of giddiness.is that side effect of paracetamol??. My health history is iam suffering from sinusitis since one year. Iam thinking tooooo much on every day for covid situation in the country and also for me and my family who are staying far from me. My query is that why I feel heavy weight in head?? with little giddiness?? Now Iam feeling very low sickness and when I inhale the air there is little burn like sensation in my nose. Why all these happening with me and what is the reason ???
