Thinking I'v got tendonitis in my left heel...doesn't hurt when no shoes on, but absolutely kills when any shoe is on my foot, right at the back of my heel about an inch or so up from the sole of my foot.

Been managing to run with it, by running it off, as soon as I put my shoe on to run, its agony, but after 10 mins its right...

Not sure whether to carry on with intense running or what yet.
