question: I have been suffering with aches in my shoulders, down my arm and my coccyx. My shoulders are really bad after sitting at my desk most of the day. My coccyx hurts when I ve been sitting. When I wake in the morning, my lower back is really stiff particularly when I bend to pull up trousers etc. I am a 50 year old woman, lead a sedentary lifestyle with not much time for exercise and I think I m around 3 stone overweight.
