physical health, exercise, injury
Seem to have damaged the tendons at the bottom of my right foot, and a little on the left. Need to give that time to heal. Started off as a pinprick pain at the bottom of my foot, has spread and become a more traditional sort of 'area of pain' and also weird stabs of pain in my middle toes (Which makes it sound increasingly unlikely to be Plantar Fascitis, which was my first bet).
Almost certainly from going on regular 3km~ walks after barely walking anywhere. Doing so in shoes with no arch support probably contributed some as well. Vans are comfy but not walking shoes.
