Hi there, as u mentioned, your job requires you to sit for a prolonged time. .. there may be mechanical load on your upper and lower back muscles... when a muscle assumes a same position for a long stretch of time and this happens everyday, there are chances of developing muscle imbalance. One group of it will go on contracting and the opposite group of muscle will go on lenghening... for your case, stretching is required at intervals whole day. If possible, seek for an ergonomic advice at your workplace... for more precise evaluation meet a physiotherapist. ...
