Well done Sarah,I have suffered from back pain on and off mainly sciatica for years,but the moment I had my op in August I had terrible back pain lower back,dull ache,completely different to usual, had it for rougthly 2 weeks,still not sure what caused it,and like you I put a post on here asking if anyone else had experienced it but didn't receive any replys,hopefully it will just disappear like it did for me,best off luck
