So just as I hoped I was getting over my illness, I got struck down by new (even worse) symptoms. Not sure if this was unrelated to the initial sickness or just a sign it had moved elsewhere in my body, but if I thought constant coughing, congestion, and sore throats were bad I was about to get shown something far worse: Vertigo. Initially very intense vertigo.
At first I assumed it was just a sign I had stared at my computer screen too long (sometimes that can disorient me), but when I took a break things didn’t improve. Instead they got far, far worse. I was effectively unable to move. Literally. I was lying in bed, and even moving my arms or legs caused the sensation to intensify, regardless of if the rest of my body remained stationary. All I could do was lay in bed and try to keep completely still while focusing on my breathing. An hour later the dizziness had subsided enough that I was able to get up and function, but I remained disoriented until that night.
In the days that followed things were never quite that bad, but I kept having spells of dizziness and light-headedness. These got fewer and more mild as time went on, thankfully, but kept me more or less incapacitated until recently. Obviously certain activities made everything worse (basically anything that involves me looking up and down a lot, or has me turning quickly).
That said, it has given me some ideas for how illness can play into a story. So often sicknesses are portrayed as the usual symptoms: coughing, sneezing, fever. All that is fine, but I can imagine how something like an inner ear infection could cause bad headaches and vertigo, which would lead to different challenges for a character beyond merely feeling bad.
