Hi MZ33 and welcome to NeuroTalk!

You've posted your question on a "sticky" thread ('Sticky' threads are created by moderators or administrators, and remain 'stuck' to the top of the listing, even if they haven't had any posts recently. Their purpose is to keep important information visible and accessible at all times) and these threads often don't get the traffic that other forum threads get so I copied your post into it's own thread on the Spinal Disorders forum. Here is a link......http://neurotalk.psychcentral.com/thread143383.html
