I am a 24 years old female. I sometimes feel pressure and sensation on one side of my body (left side), especially when lying since nine years. It gets better after taking a walk for ten minutes. But from last month I am facing these symptoms almost daily and feel pain in the sole of my feet whenever I stand after lying down or sitting for a longer time period. Moreover I feel increased sensitivity on some parts of my arm, back and leg. Now I am also having slight pain in my back with some movement.
