Hi RLR,
I had a question recently that I posted that I was hoping you could give me some insight on. Here it is:

I have a question that relates to neurology that I have wanted to ask you for quite some time. I had a bad fall on the ice 2 years ago where I injured my back. I herniated a disc in my lower back, and an EMG (?) test revealed that my S1 nerves were affected in both legs, but the left leg especially. Since my fall, I have noticed that my feet often turn bluish, especially while sitting or standing very still, and the left foot much more so than the right. I have asked several doctors about this, and the only thought is maybe Raynaud's. But I would like to know if the nerve damage I sustained could affect the blood vessels in my feet. If I rub my feet or move them a bit, they pink up again pretty quickly, and my doctor said that I had a good pulse in my feet, so they don't believe it is any blockage. Any thoughts on this? Thanks in advance! I always appreciate your explanations.
