Hi Everyone, Thank you for your advice. I have Diplegic C.P. & whilst it is mild & I can walk, I do find that as I age there are more things to overcome. Yes Kat, the sore legs are spasms & the numbness starts as well when I sit still. I struggle when I am tired &/or stressed. I do sit at the back of the room & near a door. I just find that I get self-conscious about it. Carrie.
