Last week I ended up with a nasty throat, which gave me a voice that would do justice to Wandring Star, plus a general head cold. However for the last couple of weeks my body has just been very very grumpy, aching in various places and not being at all happy. Likewise emotions have been generally dark, miserable and downward.
Hopefully that was all part of the same thing, and will now lift completely.
I'm giving running a break too. The swelling on one knee seems reduced and yesterday I managed to crouch a coupole of times, though it was very uncomfy standing up again afterwards. Not being able to get down without pain may be the price required for continuing to run.
