Schmidt, 52, of Poway, California, said she was diagnosed with TMJ disorder in 2000 due to headaches, and an orthodontist immediately recommended her for a splint, braces, and surgery.

After wearing the splint for only three days, Schmidt said, she was in "excruciating pain" and could no longer open her mouth far enough to eat solid food. Schmidt said she spent the next 17 years stuck on a "surgery carousel" with no escape, and eventually was in so much pain she abandoned her career as an aerospace scientist who worked alongside NASA astronauts.

Schmidt said her low point came in 2016. In an attempt to restore bone that had been cut away in prior surgeries, a surgeon implanted long screws into Schmidt's jaw that protruded downward out of her neck. Schmidt said she was instructed to tighten those screws with a screwdriver daily for about 20 days, lengthening the corners of her jaw to restore the bone that had been lost. It didn't work, Schmidt said, and she was left in more pain than ever.

"Every time you have a surgery, your pain gets worse," Schmidt said. "If I could go back in time and go talk to younger Lisa, I would say 'Run!'"
