I usually run 7 km in 50 minutes roughly 3 days a week. On some days I experience tight calves muscle which makes me stop running and even walking becomes painful. I get a this tingling toes before this occur. This is despite stretching and warm up I do before my run. Any suggestions and what should I lookout for?
sorry this is so brief but i need to workout but dont want anyone to suffer : make sure it is not simply a trigger point essentially a ball on your muscle you can deep massage with a ball check out the trigger point therapy workbook it might be a trigger point on the piriformis in which case dont stretch
will edit later if anyone can help please edit for me
