I know for me my issues started in the one leg and moved to the other but still the major pain is in the left. My doc said its common to spread. I will say for me with my other symptoms like when I feel out of it,have more pain in the right leg,or dizzy my major area of the left feels better. I can still feel the pain but not as severe. So I wonder when the side area bothers you if your other issues are lessen? I agree you have to really push the issue if new symptoms because what I have noticed they just blow it off or say its part of the other but not really look deeper if that makes sense? I feel for me its a connection of all my issues and that connection could help in my treatment. Now its finding the right doc to go out of the square and look deeper or solve it myself. That is what is frustrating. Take care.
