happens to me every Nov.
I get sick with a sore scratchy throat, day 2 runny nose, day 3 cough that I let last for about 2-3 weeks then I get antibiotics. about 2 weeks later-- same pattern.
wash your hands often and stay away from sick people! :-)
Maybe it's alergies or may be it is a cold. For allergies, have you tried an anti histamine of some king for a few days like Clayatine, Polaramine, your pharmacist can help you. If that is what it is, it should dry your nose up.
On the other hand, if you think it is a cold, take paracetemol at the max recommended dose for a day or so and that should dry your nose up.
Yes and quite right, keep away from sick people and don't touch the cat :-)
Hope this helps
