I’m sorry that you’re still having pain, good news that you’re ES symptoms have improved but really frustrating for you! I can imagine that it’s a real struggle to find the will to battle insurance companies on top of that, so I hope that @MGORNEAU is able to give you some advice about that. We have had some posts about appealing insurance, I don’t know if they’re helpful at all but there might be some useful info, here are the links:
