Because it's only one leg though, I'd double check things like cleat position - make sure it's the same as the other leg using the lines on the shoes or whatever. Also check that your saddle is level and you don't have a bent rail - that one caught me out touring on an MTB years ago.
Some good tips there as ever. I'll need to let it settle down before trying them out. Just walked 6 miles to an Air BnB which I'll need to hole up in and do all the RICE and anti-inflammatory food stuffs known to man.
