Can i get pressure sores from a desk job? is it possible to develop pressure sores from sitting all day at a desk and barely getting up?

Not likely: While anything is possible, pressure sores usually occur in people who either have impaired sensation in the area in question, are unable to move due to paralysis or impaired consciousness, or some combination of both. If you have normal sensation in your legs and buttocks and are not paralyzed or unconscious you are not likely to develop pressure sores.
