I feel pain and lifeless sort of feeling in my both legs, below knee area. Mostly in calf muscles. I am having this pain for more than 3 years now and 24 hours a day. In the morning, its hard to get up and do something. I am really low  in energy levels all the time. Standing for long, intensifies the pain. I have consulted many doctors, neurologists, they gave many stress relieving medicines along with vitamins but nothing helped even a bit. I want to do exercises but there is literally no energy in me due to these prolonged pain. I feel low and down through out the day at work and at home too. Please advise.
