As 237SJ says sore throats and colds are viral infections and not bacterial which penicillin and other antibiotics are used to treat.
I woke up with a sore throat, body and ear ache and nausea yesterday. Later on it developed into shivering and feverishness. I've just been taking paracetamol to sweat it out and ease the aching.
Hope you feel better soon Horseshoes.
