If it's due to a pinched nerve or prolapsed disc, you won't be
getting cramps but rather it will be more like sharp, tingling pain
that goes up and down your legs. Sometimes it's known as
'shooting pain'.
Dull, crampy pain... not quite sure it's due to your spinal
issues but an MRI / CT scan should indicate where the issues
lie. Leg pains that are usually related to spinal problems
are usually sharp and acute, but you never know! If you
haven't had at least a CT scan done, you should go get one done and
looked at by the medical experts.
I hope you are no longer wearing heels. 
And yeah, in the
meantime, eat more sodium! For all you know, these could just
be 'normal' leg cramps.
not so cheem... feels more like normal cramps which i had from
years ago (b4 back issue)... maybe cos now my food not so "salty"
