Being one of the lucky few who actually got accepted into Mayo Jacksonville, my visit was not successful in finding any relief or answers. They are very efficient at testing for the obvious but do not take the extra care to look for Zebras. My experience was they will send you to Pulmonology to look for Asthma, then to Cardiology to look for heart disease, do a basic CBC, and try to treat those issues if something obvious is found. Most of us have been through the obvious already and nothing is found, so it is devastating again when Mayo Dr's tell you they don't see anything wrong and tell you there is nothing more they can do. Continue searching to find answers from recent research, try sites like longcovidalliance.org, listen to blogs, etc. You will start to get better understanding of what's going on in your body and answers.
