So purchased new furniture today. Two chest drawers and two bedsides. Whist do was out I sneakily built a set. Wasn't heavy as build on floor and tilt up. Then got the bug and done the rest.. I kinda got carried away and was cautious on anything that may of been heavy etc. But now I ache. My knees and back mainly with bit of muscle cramp in belly. Dp is out and don't know I've done it all. Now I'm worried. Stupid I know. I'm 11.2
