I ve had a cold/ sinus infection been on zpac, dethamethazone inj, prednisone , inhalers. can t seem to get over the drainage & cough . But worse now is my tongue and throat is sooo sore, feels like it s been in a meat grinder. nothing tastes right either. what can i do for my tongue to sooth it. it looks like a geographic tongue , and it hurts so bad.
