I have been so depressed the past two years that I stopped all exercise and have either stayed in bed or sat in front of my computer. I have begun to have severe pain when walking or doing housework. I have a history of a hip replacement, broken shoulders, fractured ribs, melanoma and a brain tumor. I had recovered from all of these things. I was pain-free until about six months ago. After working at the computer I find it extremely painful to move around. I am 70-years-old and have led an active life. Now I feel like an elderly old woman who should be in a wheel chair. Can you help me? Thank you.
