Hello @jenried73 - I understand your frustration. I was denied being seen at Mayo for my conditions and concluded that they must have felt they could not help me further than my local doctors. Now, some folks keep trying and do get accepted for acute reasons, but I tried a different avenue to help my chronic pain which was the Mayo Clinic Pain Rehabilitation Center. The PRC helps long COVID patients as well. Here is a video from the Florida Pain Rehab Center's Dr. Sletten presenting on Central Sensitization Syndrome. He talks about long COVID symptoms and how the Pain Rehabilitation Center helps -

Central Sensitization Syndrome (CSS) - Dr. Christopher Sletten:

I graduated the PRC 2 years ago. It was a life changing experience and I highly recommend giving it a try if all else has failed. Will you please let me know your thoughts on the video?
