For the last couple of days my back has been so painful!! Its at the bottom, at the sides and it goes up to about half my back..also its the middle to. It just aches constantly!! I had a long car journey saturday and i was driving...and after about 1.5 hours in the car at a time i had to get out coz it felt like my back was bending in half! Yesterday i went into work but only last an hour and a quarter coz i was in so much pain! I dont understand what ive done to it. Ive got ibruprofen tablets and ibuprofen gel to rub into my back, and paracetamol...But still it hurts.
