I have been struggling with ongoing cramps which occur just below the ribcage (where the highest of the sixpack muscles should be). They are extremely severe and will stop me running and if it's particularly bad I won't be able to run again without pain for a week or so. Has anyone else experienced this?
I spent years rockclimbing and doing lots of pullups/campus boarding but sort of ignored the core muscles (keeping your feet on the wall is for weak people). So I'm wondering is it a muscle imbalance due to tight shoulder muscles?
Cheers,
Matt
