hi, my partner has experienced drainage of liquid (not thick) yellowish/orange fluid from his nose. It is more pronounced when his head is down, and happens a few times a day. A few headaches lately but nothing major and no other symptoms. He had sinus surgery a few years ago and read online that it can be a leak from spinal fluid to the brain, but it could be nothing I suppose. I told him to see our GP tomorrow but he wants to wait a fw more days. What would you advise? Thank you
