I don't know how bad the pain your feeling is, but I had throat problems in January that never seemed to go away. Eventually I had to have my tonsils removed. In your case it could just be a result of being sick, but if the pain is very bad like mine was, maybe you should get it checked out.
I get this a lot. It feels like your swallownig shards of glass. Not fun. I use this throat spray, its only a quick fix, but it helps get me through it. Gargling salt water is always a good idea too.
That was exactly what I was feeling. Sometimes you can get through it, but sometimes your tonsils just get filled with the bacteria and there's nothing you can do about it but to have your tonsils removed, depending on how often this happens to you.
