Anyone ever injure themselves during a crucial phase of their HT building? I'd waited 4 to 6 months for this dealer to recieve my order of 18 movie poster size pockets. I went right down to get the box, it was long and fairly heavy it turned out. I not only lifted it but also had to raise it up to chest level to clear an obstacle on the way out the door resulting in throwing out my back! For two days my back's been wrenched out. I really wanted to do necessary cieling decorating on my HT. I'll be 51 in July and not sure if my back will heal up like when I was younger. To to it off, one of my knees has had arthritis or something for weeks. Maybe I'd wrenched it while in bed? Os
