Yea
@Sidney, it's so weird - I definitely felt PEM starting a day or two later - can't remember when it really started. Although, the day of, I felt a little like I was in shock right after - I kind of embarrassed myself in a meeting because I got confused (but covered it up well with a joke - I'm good at that with all my brain fog!) and then had a terrible headache that evening.
The good news is my ankle barely hurts anymore, swelling is down, and just a little bruise left. Unfortunately, I'm still in a bad ME/CFS flare. My arms are so sore that I had to swap out a heavy fork at dinner the other night for a smaller, lighter one. Felt like I was doing reps with a 20 lb barbell with every bite.
I know better than to use the word 'cause' as well, I should have said 'related to' or 'associated with', but we're casual here, right?
