For the past like 5 years, I'm on the computer most days, which requires sitting for HOURS. I'm a young guy, 19, and I'm already starting to experience lower back discomfort/pain. I wouldn't say it's so much..a shooting pain, but just feels uncomfortable and irritated. I'm sure I'm not the only one here who spends countless hours on the computer. For those of you who have a similar problem. what do you do?
