For about 12-15 days my back of the head pains when I look down to study. Initially the pain started in the head .and then when I would study for some hours my neck and shoulders would become stiff due to which the back of the head started paining. After 6-7 days the pain started even in lower back when I would sit to study. On walking and normal work it does not hurt but sitting anywhere for sometime makes my back of the head feel tight, and stiffs my neck and sometimes causes lower back pain. How to cure this. I had taken muscle relaxation tablets but their is not much improvement. I had applied heat even and started exercises and jogging as well in between studies. Exams are near so I can't help but sit to study Nd hence feel the pain.
