I am having fever and headache from 2 days, I have taken rest of 1 day and took paracetamol and benadryl , today also not feeling well , I don't have fever now but feeling tired. I want to take 1 more day rest. Is there anything else should I take? Also, need medical certificate stating this to get leave from the college. If someone could provide me certificate stating the cause for the absence , I will follow up on the consultation, college will need valid proof.
