I'm not a dr. just a paramedic/ combat medic but I've worked in the ER and urgent care clinics. first off keep taking your leviaqin, drink lots of fluids, and an anti-inflamitroy will help your throat. Motrin 800mg will work depending on what other meds you have. If eating is hard for you try getting a lidocaine mouthwash to gargle with before you eat, it's sold under hurricane spray or vicks cloraseptic. If you have a fever over 103 call your doctor. What other meds did they give you and in what dose? Adding anti inflamitorys can be dangerous unless I know what else your taking
