I have been fine up until week three (just started it) but knees are now in lots of pain! Skipped two days (have been doing every other up until now) and went out today but had to stop with the jogs half way through and walk as too painful. When I was little I used to wear leg splints as I have dyspraxia and used to walk incorrectly. As a teen I then had heel cups to correct my gait (I used to walk with too much pressure on my big toes and do not bend my feet properly). I have not had issues as an adult (now 30). I am not really sure whether this is just normal 'runner's knee' or if I should check out how I walk/run? I have done the wet foot test and it appears I have high arches. Advice would be very welcome.
