My complaint started with a sinus infection, took a course of Keflex, the last Saturday night(8days) ago my throat started hurting. The pain was incredible and still is! Went to Urgent Care Friday, got Amoxycillin and Motrin for pain. Shouldn t most of the swelling a pain be gone by now? I can t get enough fluid down, unless it s hot. It s weird, every other time cold felt better on my throat, now it hurts it. How long am I to wait before I seek more help?
