Hey Nessy...
did that stuff help? Passing out from pain sucks - I really suggest that you start bumming around the house - at least short term. When I pass out it is either because of pain, blood pressure or both - so could be worth getting your bp checked - especially as you are worse when upright than when flat (same as me). What does idiot PM say? it's your anxiety, right???
Hope she is doing something
Love ya
