Greg Schroeter's bout with COVID-19 was relatively mild.

But the other problems it triggered left him hospitalized for nearly three months.

The 51-year-old from rural Humphrey, Nebraska, said his recovery has been long and emotional.

"I went from basically being bedridden, and one of my physical therapists stood me up," he said. "And I looked him eye to eye and I knew I was gonna walk again."

Schroeter documented all his milestones at Madonna Rehabilitation Hospitals-Lincoln Campus: the first time standing, walking on a robotic treadmill called a Lokomat, and using a walker and walking on his own.

"It's three and a half hours a day of pure hell, but it's worth everything because I'm going to walk out there," Schroeter said.

In November 2020, his wife Kimberly Schroeter, a registered nurse, tested positive for COVID-19. Her symptoms were mild. They wore masks and slept in separate bedrooms.

"I guess I thought I was out of the woods. I was on day 10 of quarantine," Schroeter said.

He was working outside when suddenly he felt pain in his legs. A couple of days later, he could barely move. On Nov. 23, he was taken to Methodist Hospital in Omaha, Nebraska.

Doctors told him he developed Guillain-Barre syndrome, a neurological disorder that attacks the spinal cord causing paralysis. It was apparently triggered by his exposure to the coronavirus.

"I never would have gotten Guillain-Barre if it wasn't for COVID," he said.

The disease soon began affecting his breathing.

"This is the most painful thing I've ever experienced in my life, and I wouldn't wish it on anybody or my worst enemy," Schroeter said. "It is absolutely awful."

Kimberly Schroeter said she was thankful Greg didn't have to go on a ventilator.

"For some reason, he escaped that twice and that was pretty amazing," she said.

Schroeter also developed a pancreatic cyst that doctors operated on. On Jan. 8, he was well enough to be taken to Madonna.

"I was basically helpless," Schroeter said. "No matter how hard I tried, I couldn't move."

Dr. Paul Krabbenhoft, Madonna's Spinal Cord Injury Program medical director, said Schroeter's case is not unique.

Since the pandemic began, Madonna staff in Lincoln and Omaha have treated 105 patients for post-COVID-19, many with severe side effects.

Krabbenhoft said they have also treated other Guillain-Barre patients. "Something that causes the immune system to respond and then it gets out of kilter and it starts acting on and attacking the central nervous system," Krabbenhoft said.

Schroeter is grateful for all the support from family, friends and co-workers.

"I feel like the prayers that were given to me and the Methodist Hospital team and the Madonna Hospital team, I believe they saved my life," Schroeter said.

For every milestone Schroeter recorded, his wife would send him a text.

"I would say, my heart is fluttering," she said. "Fluttering was like my word to him every time he did something so amazing."

Schroeter will soon reach another amazing milestone: going home two weeks ahead of schedule.

"He's my hero," Kimberly said. "Everything he's been through and he just never ever gave up. I guess I could say that I think I fell in love with my husband all over again."

WASHINGTON (AP) — U.S. health officials say Johnson & Johnson’s COVID-19 vaccine may pose a “small possible risk” of a rare but potentially dangerous neurological reaction.

The Centers for Disease Control and Prevention (CDC) said Monday that it has received reports of 100 people who got the shot developing an immune system disorder that can cause muscle weakness and occasionally paralysis.

The reports represent a tiny fraction of the nearly 13 million Americans who have received the one-dose vaccine.

The New York Times and The Washington Post report that the Food and Drug Administration is planning to warn that the J&J vaccine can lead to an increased risk of a rare neurological condition known as Guillain–Barré syndrome.

The Mayo Clinic describes the syndrome as a rare disorder in which your body’s immune system attacks your nerves. The organization said weakness and tingling in your extremities are usually the first symptoms, and that the sensations can quickly spread, eventually paralyzing your body.

The government said the vaccines most used in the U.S., made by Pfizer and Moderna, show no risk of the disorder.
