I'm a ta so only been back at work over a week, this morning before I started I was emptying the dishwasher in the staff room and my back went, I was meant to be going on a trip today I work 1:1 And want to be back at work asap. I've got the doc at 5pm I've been laid on my wooden floor all day and taken pain killers. It's agony what else can I do to feel better?
