<human>: I had sinus surgery a year ago, and I'm starting to have problems.

Backstory- I collapsed the sinuses under my left eye, and had to have them rebuilt. The process that they used was to make a cut in my gum line to avoid unnecessary visible scars. The result of this is a vein of scar tissue that runs beneath the skin along the side of my nose and is invisible to somebody looking at it, but extremely raw to the touch (under the skin) and hurts like a bitch on seemingly random days. The process reshaped my eye, so I can no longer wear contacts and the cheek bone is changed in shape, though not so obvious to an unaware person. Other than that, I don't know anything about the surgery besides that some kind of foam was used?

Problem- I caught a cold a couple weeks ago, and it doesn't want to go away. Its just been congestion after the first couple days, which is normal for me and is a hereditary issue. But as of last night blood started appearing in the mucus and has been persisting into the morning. I no longer have insurance and have financial difficulty, to explain why I'm asking here. We heat with a wood stove though, meaning the air is unusually dry, so that could be a perfectly logical explanation as well.

In the end, I don't know if its just a shitty surgery to have thats going to leave me with problems for the rest of my life, or if this is unusual and I should go into the doctors, spending a shit ton of money that I don't have to be told "no, its nothing. here's your bill for my 5 minutes of pretending to care and your 90 minutes of waiting to see me."

Can you summarize the given text in a few sentences?
<bot>: I collapsed the sinuses beneath my left eye a year ago, and am having problems that feel related but could also be explained rationally by the weather, lingering cold symptoms, and the low humidity of my house.
