Mine was 1.5 years...but as time goes by I don' really know if I have leak anymore, actually, I don't know what is my problem (even the doctor does not know)...For now, I'm just gonna say I have infection and see if it will heal after a while. Actually, I have never had fluid coming out of my nose, just something that looks like mucus because it is kind of sticky (sorry...).
One thing that bothers me a lot now is the tinnitus, which I've had for the last 5-6 years, but currently since I've had this condition, it is getting to very bothersome when I talk on the phone or when I just have a conversion with someone. The noise actually sounds like bubbles and water fall and it it is excited by noise then I'm feeling like there is fluid coming out from the inner ear...however, I do not know if that is happening either. The other thing is my head is very sensitive to bumps, touch and motion. Also at night, there seems to be some pressure (or pain?) in the back of the head when I lay down sleeping.
The last two symptoms (head sensitivity and pressure), I've checked with people who have leaks (on the Brain Talk Community forum, there is one group specifically for CFS leak), some have leaks for over one or two years, they do not have those symptoms. They usually have headaches, neck stiffness, lost of balance/dizziness, but not the head sensitivity and pressure. These are the people who have leaks due to various issues, not just because of AN. There was one person who had the AN surgery about 20 years ago and he also had leaks right after the surgery, but some of them let it heal by itself by just resting. However, most got a procedure called "blood patch" to fix the leaks.
Can this be the fat infection like my doctor initially mentioned? However, he does not seem to mention that anymore and I guess that since I already got the spinal tap with negative result, he probably ruled that out because if the fat was infected, then it probably should have gotten the CFS fluid infected as well.
I'll keep update this post as to my condition.
Thanks to all those who have followed this and given me advises, etc...
