i had a nose operation 3 yrs ago to carve out my cartridges as i was hit on my nose (the guilty party was found guilty at the crown court)... shortly after my op, one day my nose was dripping like a tap not turned off properly and was bright yellow, i thought 'thats strange!', my friend who had a similar op and he said that its the brain fluid that was dripping out of your nose!! but none since then. i had a awful cold last week and today it was doing it again, my phelgm was bright yellow and water dripping out of my nose - anyone had this experience?
