Your headache sounds awful. I can't imagine suffering for 2 years with it.
I did post another update on my headache on 7/12. You can find it here:
http://www.medhelp.org/posts/show/100419. The doctor is no longer so sure about the aseptic meningitis.
Bacterial meningitis is a very serious condition, more serious than viral/aseptic meningitis. Maybe that's what your doctor was thinking when she said you wouldn't be alive now if you had meningitis. Do you know what type of meningitis it was that the other person you mentioned had for 8 months? I also know that there are conditions where the headache or meningitis persists even after the infection is gone.
Are you saying that your headache started only after your Rhinoplasty? Or changed, worsened, etc. If that's the case, it would seem there is some sort of connection. Also, is the drip you mentioned yellowish/greenish or clear? I ask that question because CSF can drip from the nose and be mistaken for clear nasal secretions. However, since you said it has an awful odor, I imagine it's not clear. Have you been treated with an antibiotic for it?
Unfortunately, I am not a doctor nor very educated about headaches. I've just read some stuff on the internet as I've tried to figure out what might be causing my headache. What does your neurologist say about your headache? Besides the 2 MRI's and CT, have any other tests been done?
In my searching, I found a document that classified every type of headache there is, both primary and secondary. I'll take a look at it and see if there is anything about headache following rhinoplasty. If I find anything, I'll write more.
