Hello everyone. I had a non-aneurysmal SAH three years ago, I spent 10 days in the ICU. It took a long time to get my strength back but I so far have no lasting issues, except for the headaches, which I'll get to in a minute.
The cause of the bleed was "unknown" and also "unknown" was how it repaired itself. Not sure about all of you, but this not knowing is the hardest thing for me about this experience. I feel the need to know what caused the SAH in the first place. Was it a deformity? Something that is likely to rupture again? I've read all the studies and I know that statistically these things are (generally) one time events. But, at 3 years out, I would really like to know why I continue to get random headaches - my doctor 3 years ago told me not to worry about headaches, unless I get one that builds with no relief, which of course would mean I'm having another event. Trouble is, every time I get a headache I am instantly transported back in time and place to the original bleed, and I find myself working out in my head how I'm going to get myself to a hospital. I work as a hiking guide and am out in the wilderness much of the time, getting to a hospital isn't always easy, or even possible.
I know I had a brain bleed, and I know that when this happens it alters physiology, but I have yet to have someone tell me why I get these headaches. If I understood the physiology, the "why" of it, I would be better able to deal with the aftermath of the recurring headaches. Sometimes they are like an ice pick being driven into the center of my brain, and they last only seconds, other times there's a tightness, pressure, dull but constant pain, dizzy/foggy, associated mild nausea, and it lasts hours. The end result is always the same, though, I am left shell-shocked, I feel quite vulnerable, and I don't want to tell anyone close to me because I don't want them to worry or treat me like I'm a grenade about to go off. I don't like going to bed at night hoping I'll wake up in the morning, not knowing if I will. I'm guessing those of you who have had these know what I am talking about.
Can anyone explain to me why we get these headaches? The physiology of it? I honestly think that if I knew the answer I would be better able to deal with the aftermath. The only answer I've gotten that makes some sense is that blood in the brain isn't absorbed over time, it turns into scar tissue. That could explain the pain, perhaps this scar tissue is affecting a related nerve. Maybe my CSF is out of whack, I had a lumbar drain while in the hospital, and maybe since I'm always moving between sea level (visiting parents), living at 7,200', and working up to 14,000', it somehow causes pressure problems. I also have hypertension, which I treat with medication, but my BP is all over the place, maybe as my BP fluctuates it wreaks havoc. I know it's not an easy question to answer.
The attitude of some of the doctors I talked to after my event was - "you are here talking to me, you are fine, you should see most of my other patients, consider yourself lucky." Others have been more understanding, but they have told me that science just doesn't know enough about the brain to explain it all.
Any insight would be appreciated. Thank you for reading all of this.
