I would like to spend more time on the messeage board during a setting. I get interested in posts, but I start hurting like crazy. It's hard to even sit at the computer very long. I can feel bones just crunching in my back. I use a pillow behind my back, but it don't help much. Knees start hurting too, from sitting and having them bent. I try to stay on for a little while and rest also, but soon as I sit down, my back starts hurting right where it left off. SOOOO aggrivating. Maybe I need a better chair. I just have cheap chair from wal-mart. Anybody have any suggestions as to how to make yourself more comfortable while on the computer?
