Nose stuffed, and minor yellow mucus, i can smell blood, and a terrible headache?

So im 24 years old, and i have been having this issue since like 2006. The issue I have happens a few times a year. It starts off with a slight headache and not just any. I feels like something is cracking, like something in my head or around my nose is giving way. Not like a crack like i need to run to the hosipital but like something is clearly expanding or there and is a build up and something is givin way slighlty. Then i smell blood, and this worries me a lot. I know if this was a standard headache why would i be smelling blood...this isnt normal. Then today i happen to just cough and had yellow mucus come out. This whole process usually last for like 2 or 3 days. I dont really cough like that, im clearly not sick, but my nose is stopped up (always, with a faint smell of blood)...nothing comes out when i blow my nose, and the constant pressue is there in my head like something is just getting larger and larger. I dont know what it is, or what to do...i usually sleep it off but i do wake up from time to time because of that cracking feeling and pulsing in my head. Has anyone had this, dealt with it. Ima see a doctor again about this but i need a better answer than "its just a mirgaine" cuz i had those before and im sensitive to everything...this what im experiencing is far from it.

By the way, i had a nose bleed one day (i will give detail) and i was actically able to pull blood out, yes, i blew my nose, red stuff was just hanging and i just pulled!!! and i felt a great relief from my head and didnt have a headache...its was a dark red, and stringy. Am i turning into a zombie? this only happened once tho...in 2006
