Just in case you haven't done it yet, go see the doctor when you get those aches, since they might not be benign. One of the darker sides of sitting all the time is haemostasis: your blood isn't moving enough. That's a condition which can lead to deep venous thrombosis - blood clots. You really, really don't want a DVT. Stay hydrated and move - preferably every 20-30 minutes.
