I am a 23 year old male. I am on day 4 post tonsillectomy surgery. My throat hurts real bad. I can't even swallow a glass of juice. But of late my back teeth are aching real bad. I have no cavities or had any issues with my teeth before. The aching along with my throat pain kills me. My doctor has prescribed febrex 650 once after breakfast. What kind of painkillers can I use to lessen the pain. Especially during the night I can't even handle the pain as it is at its peak. I'm gargling three times a day with hydrogen peroxide drops in water. Please help. Is this normal. How much time does it take to overcome this isane pain.
