I bent down to pick something up from the floor on the 23rd and since then I’ve had intermittent back pain. However, today I cannot straighten up, walking anywhere is so painful. I’ve tried deep heat, paracetamol and ibuprofen but nothing is helping. We’ve even had to cancel our Boxing Day plans because I can’t do anything. The pain seems even worse than when I woke up. Any ideas how I can ease it?
