Hi all, I've sat watching corro tonight and suddenly it hit me, a sensation I've had a little throughout the day, a strange ache in the outside of my left calf come ankle, I dont know why but I felt a need to press my left bum cheek (know what this may sound like) and kind of knead it with my knuckle, there's a strange sensation I've not had before and after a little research on the net it's led me to think it could be Sciatica, could this be the reason both my legs locked up so painfully on Saturday ? Sorry about the 100's of questions but it's a process of elimination, Craig.
