I get pins and needles in my left foot after running for about half and hour, eventually my whole foot goes numb, and I get a burning pain in my calf. I've recently been referred to an orthopaedic surgeon, who thinks that it might be a condition called exercise induced compartment syndrone.
There are many descriptions of this condition on the net, if you think you've got it then badger your GP for an orthapaedic referral, and if you can't bear the waiting times, BUPA charge £110 for an orthapaedic referrral.
Unfortunately, the only way that this condition can be managed is by surgery, post surgical outcomes are however excellent.
My foot also goes numb, after about 35 minutes of running. The numbness stars in my big toe, and then travels back towards the heel so that my whole foot is numb.One time I continued to run and the numbness started to rise over my ankle - next day I couldn't walk due to a very painfull achilles/calf.
I've seen a consultant podiatrist who believes that the numbness could be caused by a condition called exercise induced comartment syndrome, and I have been referred to an orthapaedic surgeon for a definitive diagnosis and possible surgery (fasciectomy).
Some things which delay the numbness is by running with loose laces, or try skipping a few holes while lacing up. A wider fitting trainer also seems to help.
