Big hugs (the non-hurty kind). You are good and you are brave to try something new to fight for your legs. It is so hard to know what to choose when the choices are so not-great. When will you get your first blocks, do you have an appointment yet? and for the pasting out ... everything other cause has now been ruled out, right? (Vitamin B-12, blood pressure, etc etc). Pain does such awful sneaky things to our brains and bodies...
