This stemmed from a few factors. My cough feeling like it had changed. The fact that I felt like I was getting much, much better, and yet now feel sick again. The fact that I've been feeling like I've been burning up. (Though, apparently, that doesn't mean anything because according to the thermometer, my temperature is approximately 98.96--a little high, but I'm fairly certain that's not only within the margin of error but also practically expected of my family because if I'm not mistaken our temperatures always run just a little bit above the norm.)
Conclusion: uncertain. It remains a possibility, but not a probability, if that makes sense. It's something to be on guard for, certainly, but at this point I wouldn't be too worried about it. I don't have most of the symptoms that would be expected of a bacterial infection following the flu. I have a cough. And a runny nose. But that's it; I'm otherwise feeling healthy. Plus, we're not out of the zone where the sickness began, especially not for me.
My immune system works in a particular way: I don't get sick often. I really don't get sick often. If most people got sick twice a year I might get sick once every two years. In that I do get sick, it's just that it's so infrequently compared to how frequently others get sick that I might as well not get sick. My body does a really good job at rejecting the germs, I guess.
...The problem is. When I do get sick. I get sick badly. My symptoms are often much worse than typical...and it lasts much, much longer than it by all rights should. So say the average length of a cold were one week; I might have it last three to four. A flu can last up to two weeks (so, circa this Thursday is when it'd be done for a normal person), so for me it wouldn't surprise me if it took six weeks to fight off.
So in other words. I get sick a lot less often than normal people do, but when I do get sick I get sick a lot worse than most people do; my immune system seems to be trained ridiculously well to prevent being compromised but have only minimal training in how to respond when compromised.
What I'm getting at here is, there's a large chance it's just the flu right now, so I'm not too worried. Also, I hate the thought of taking antibiotics in general. They kill all the good bacteria which is a pain to replenish with probiotics; I don't like the process. That, in addition to the obvious risk of administering antibiotics unnecessarily and thus increasing the risk of bacteria developing immunity to them.
I feel like those are fairly justifiable reasons to not just automatically take antibiotics here. So for the moment, I'll just put the possibility aside and assume it's a stubborn flu. It could be a bacterial secondary infection, bacteria infecting me after the flu taking advantage of my weakened immune system. But it's not that likely at the moment.
Anyway.
I did that instead of blog; I could blog now but I should be going to bed. As-is, this is a way longer entry than I was intending to make.
