I've had an achy back for a couple of days which I put down to the fact that I now have a cold. I sneezed last night and got a shooting pain in my side and it still aches. It feels like an ache in my hip that goes round to my back and is painful to walk. I've got cysts on my ovaries (which is why I'm huge already) so maybe one of them has popped or I've just pulled a muscle. Could it be something to do with ligaments??
