Ah... not as gross as poo, but close! 
My way to deal with a common cold is mostly to wipe my nose as required.
If I get feverish, I use paracetamol (that's Tylenol, for you murricans) 1000mg once every 8 hours, or just once and never notice myself getting feverish again.
If I feel a sore throat I use Ibuprofen 200mg instead. Same time between doses.
If my nose is particularly stuffy and wiping seems to do nothing to improve the airways situation, I grab a Cetirizine pill and that usually (but not always) helps. If no chemical helps, there's the old tissue up the nostril trick that, somehow, apparently keeps the other nostril unobstructed for a while.
