Ok, I'm crap at pain and being injured but this hasn't been a problem before as I'd been blessedly injury free.
Last Saturday we were running the Wasdale horseshoe and got caught out by a thunderstorm and hail. The descent back into the valley was steep, slow and I got very cold. I had very sore quads and calves for the next 3 days which gradually eased through massage and avoiding anything faster than a stroll.
Today I tried a lunchtime run at very gentle pace but had to stop every 800m or so to stretch enough to continue. I was hardly moving faster than walking pace to stay warm. The cause of the stopping was a sharp pain which is under my right heel, right at the back of the sole. It feels like I'm standing on a biro-lid-sized-stone. I guess this has been masked by the sore legs earlier in the week?
Any diagnosis, advice or treatment?
