I have difficulty walking (gait disturbance) and balance (Poster instability). My PD causes me to take small steps and a fast scuffle with my feet together, bend forward slightly at the waist (stooped posture).I have trouble stopping and when I do, I hang on to some thing solid (to gain balance) and regain my composer and try to take larger heal down first steps. Then my bad right leg begins to drag forcing me to land on my right front foot and toes, causing discomfort in my calves. I have a severe walking problem. During my "Off Time", I have difficulty in taking regular steps with the right leg due to pain. My right foot cramps and turns inward, my big toe turns up in my shoe. My right leg calf muscle gets sore & camp; painful. Wrapping the right leg calf provides some relief.
