Thank you for replying!! I haven’t checked the site in a few months, but I checked it again today because I am going to another neurologist. I contacted a few other people with your name because I have been so desperate for answers. There is another lady from Puerto Rico on a different site I have not been able to communicate with who has same burning symptoms when sitting. If you are on Facebook maybe you can send me request or your email address instead of waiting for replies on this page.
