I had a head cold about a week ago, tired, coughing, blocked nose, headaches.
I am without most symptoms now (my voice is still slightly "husky") and I was feeling OK this morning.
But, a few minutes ago, my nose just started running with a thin, watery, clear/slightly greeny-yellow tinged liquid. This dripped for about 20 seconds, then has stopped. There is a slight smell to the fluid, and it evapoarated / dried up fairly quickly on my finger.
Is it CS Fluid ? Should I see a doctor urgently? I have no head pain, or any other pain. Its the first time I've ever seen this fluid from my nose.
