Exactly this happened to an artist employing my girlfriend, many years ago. This artist was told it was all mental illness, was treated with rudeness and contempt by her doctors, and ended up in a wheelchair, which she had to pay for herself as her doctors wouldn’t sign off on it.

Then she went to yet another doctor, and got the Lyme diagnosis. She lived with a few miles of Lyme, CT and liked hiking, for God’s sake!

A month of antibiotics, and she was out of the wheelchair. Last I saw her she was still walking with a cane, though — in her 30s.
