Hi Baba, I think that plotting a roadmap for this disease is tricky. You might come close to a consensus but there are many variables. Myself, I have two steady symptoms(leg weakness & numb toes) and the others change from one week or month to the next week or month. Lumbar , hip, knee, butt pain, tenderness of skin, all take turns at the front of the line.It's wierd that what you would think is bad could be good and visa versa. Good luck, Ken in Texas
