I'm in a hurry because I'm studying for an anatomy test and I shouldn't be online goofing off. But I came across this and the person who said they knew 'exactly' what you had is so freaking wrong. All they could see was a protruding disk. Listen, it could be a lot of things, most of which are not going to confine you to a wheelchair. My educated guess is yes, it is probably from sitting at a computer for too long with bad posture. Try to be aware of your posture or practice yoga. Because it may not hurt now, but if it sticks out any more or if you sleep funny on it, its going to start to compress nerves and believe me, you don't want that to happen. I literally just made a stupid account on this website to let you know that you do not have the same unfortunate illness as that person.
