hi sdkashif,
thks for the reply.
piriformis syndrome was tested +ve on his 1st visit.
resolved in 1/52+ after daily stretching.
the problem is, pain is still on left buttock, but not from the piriformis.
the 3 tests that u suggested are new to me,
I would like to re-ax it on his next visit,
thanks for the suggestion.
