Yes, it is probably aggravating it.  I can't sit normal at all anymore.  I will be saving up for at least a 28 inch flat screen I can put up and then can change positions as I need to.   Of course a running rig will be next on my list, mine crapped out months ago.  Haven't needed a rig throughout winter but as we get closer to summer I will need to get some wheels.  Then the flat screen LOL
