I have either a severe sinus infection or mono(will know tomorrow), but the doctor prescribed me BP Poly 650 every 4 to 6 hours, corzall liquid every 4 to 6 hours, lidocaine every 3 hours, and promethazine 25mg at bed time, I broke out in a rash from my prior antibiotic and have to take 2 benadryl until it's gone, and I've been taking ibuprofen to relieve the swelling and help my fever.
