Ibuprofen won't really help in this case. It's an NSAID that's primarily designed to deal neuromuscular conditions and it is not recommended for use in conditions related primarily to inflammation without a clear neuromuscular cause.
Paracetamol would be the better bet in this case.
I don't know about the correct medical opinion on this, but ibuprofen definitely works for a sore throat. Apparently drinking pineapple juice is also more effective than cough syrup, and I've recently discovered chocolate works quite nicely.
I've had a sore throat since yesterday, but I haven't felt the need to take time off work. I am, however, not a man.
