Quick question I've started to develop a tendon (almost like heavily bruised) area on the heel of my right foot. It's been there for a week or so, but I did a long run wednesday, did some boxing yesterday and this morning I couldn't put any weight on the thing. It seems better now however. In the last week, and wednesday for example, it's been sore, however a bit of a warm up or a few hundred metres and it's good to go. Has anyone had anything similar. I assume not running is the way to go for a week or so.
