At the end of last night club traing run I got a pain in my right heel. It's at the back of the heel on the right hand side. I can feel it when I'm standing with my weight on both feet; when I lift the foot off the ground the heel throbs a bit and then calms down.
Is this likely to be a simple bruise or could it be something more serious; I've got a 27 mile off road race on Sunday. Any helpful thoughts, pearls of wisdom, useful tips would be much appreciated.
Cheers - Raymond
