hi gawaine i don't mean only limp by claudication.i used the worls of pt coz instead of tinging and numbness she was filling like that.when she was alright i.e able to walk and stand without any symtoms i started bridging but stipped again coz 2 days earlier she climbed 30-40 steps and again developed acute pivd with tinging this time.right now i have puted her on traction,deep heat and rest.
