Recently i dusted my room and cleaned the fans which had a lot of dust over it. Unfortunately i didn't put on a proper mask. A day later i started having allergy symptoms like change of voice and then blocked noise and sinus. So today, before sleeping, i took a cetirizine tablet and ambroxol syrup. I fear i might get an infected throat as well. Do i need to take antibiotics as well? I have GERD as well.
