Had a cold, and bronchitis and was treated with prednisone, antibiotic and cough pill, felt better but never quite got over the sniffles and congestion. Have had a clogged left ear, and Tuesday, got vertigo and went to ER for relief. Followed with GP and he put me on antibiotic but still today Sunday, have buzzing, clogged left ear. Feel slightly off (dizzy) and periodic minor nausea. Need to go back to work, but fear vertigo again.
