Earlier today I bent down to move something and felt a twinge/something 'go' in my back. As the day has gone on its got worse - stiffer, more painful at times.
It doesn't hurt all the time ie. when sitting still/ standing still its OK, some walking is OK. I can even stand on one leg and lift my other leg up, bending my knee and holding it to me IYSWIM.
When it does hurt is lowering myself to sit down, trying to stand up from sitting and when I bend down forwards eg. can't bend to open the oven door or pick something up off the floor.
I've taken Ibuprofen and Paracetamol and been holding a hot water bottle on it.
Have I just pulled a muscle? Will I be able to get out of bed tomorrow?
