Hello, has anyone been diagnosed with rhinitis before?

Today at work I stood up after bending over and my nose poured with what looked like a white/yellow watery liquid. It happened twice with no warning. Luckily my mask caught it but where was a good amount. I contacted my dr as ive had what I think was a tension headache for a couple of weeks on and off and he’s come back with rhinitis and suggested a spray and antihistamine but if it gets worse or doesn’t settle let him know.

I’ll be honest I googled and I’m terrified it’s a CSF leak
