It looks like you are anaemic. If you have back pain after you sit for long hours then it is due to your haemoglobin levels as it is important to check that. Anaemia always leads to the symptoms of being tired and also having back / leg pain though there may not be any pathological reasons for back pain. It looks like
you are anaemic. And also you have to check with your vitamin and calcium, if the bones are weak then automatically the pain gets triggered more as there is less energy during any metabolic activity.
