I've discovered more recently that the physical effects I get are much more than I initially thought. When I was on holiday, my friends and I decided to climb a mountain - 1465m to the top, 12km total walking distance. Even before ptsd had a significant effect on my life, I would expect to feel sore for a couple of days after such a climb. This time, we climbed on Saturday and I was in significant pain from aching muscles and just wiped out energy-wise until the Thursday. The climb itself was more tiring than I'd expected, as I walk a lot each day normally, so I thought I was fitter than I turned out to be. Is this result from exercise normal for ptsd? I am also experiencing the same effects having run around chasing an escaped wallaby for 4 hours on Saturday. I didn't feel tired while doing it - I guess it was the focus and adrenaline - but I have been laid up since and I ache everywhere. I'm wondering if I should expect to feel so tired and sore for so long. Also wondering if it's the ptsd effects or age-related effects! I understand that because I am so tense all the time, my muscles are working harder and have less time to rest, but why does a bit of strenuous exercise have such painful after effects? It's really bugging me!
