 Mom's sick for 10 years until repairmen find something very wrong in her furnace. Cathy was sick and tired of being sick and tired. Doctors turned her away, her relationship with her daughter was suffering, and she was miserable. Eventually, she accepted her fate. If no one could help her, she would help herself. But she never expected this. When Cathy heard the doorbell ring, she dragged herself upright, hunched over, and coughed heavily. Looking for her walking stick, she pulled herself up from the couch. As she shuffled to the door, her cane scraped and tapped against the wooden floor. The contractors had arrived. When they made their way upstairs to finish the job, she retired back to the couch, her usual spot. She closed her eyes, hoping that a nap would alleviate some of her aches. Then, she heard them scream her name. Cathy Wilson was an ordinary 41-year-old who lived in Shelbyville, Indiana. She had worked hard to support her family. She was no CrossFit enthusiast, but she lived a moderately active life. Ten years. Ago, she fell ill unexpectedly, and she had convinced herself that she was just run down from stress and work. But her daughter was worried, and she had every right to be. Cathy gulped down a cocktail of vitamins and over-the-counter medicines, in an attempt to recuperate. She took vitamin E, vitamin C, vitamin B, zinc, iron, but none of it seemed to help. After a few weeks her daughter, Ashley, forced her to go and see a doctor. But the doctor just confirmed what she already knew, and she was given a sick note to take a few days off from work to rest. But Cathy's illness was unshakable. Cathy was pale and had random bouts of exhaustion. Her appetite vanished, and her health continued to decline. Ashley was growing increasingly worried. Weeks after her first visit, she dragged Cathy back to the doctor. They were surprised that a strong, young woman with a healthy immune system like Cathy, who should have overcome the flu weeks ago, was still deteriorating. Now, they were growing concerned too. Dr. Mary Beth Hensley, beginning to take Cathy seriously, ran blood and allergy tests in hopes of picking up any disease or intolerance. All the tests confirmed that Cathy was a healthy woman. They didn't have a diagnosis. But they decided to try an elimination approach, so Cathy was put on several different antibiotics. Dr. Hensley had hoped that Cathy's reaction to the medications would give her an insight into her ailment, but instead, the opposite happened. Cathy started to feel worse instead of better. She had body aches and could barely keep her eyes open. Then the mystery illness started to take a toll on her mental health. Her friends and family members started to worry. Maybe the illness was all in her head? But no, Cathy knew her body and she knew something wasn't right. Ashley witnessed her mother's deterioration first hand, and she also knew in her heart that something just wasn't right. Cathy determined to get to the bottom of her illness, searched for her symptoms online. She spoke to experts in online chats, and she tried herbal treatments and natural remedies, but nothing seemed to be helping. As time went by, more and more people lost faith in her, and no one could give her answers. She had never felt so alone before. Maybe it really was just all in her head. Cathy visited her doctor regularly over the next 10 years. Dr. Hensley provided Cathy with the best care and tested for everything that she could. She went to great lengths to attempt to diagnose Cathy. She insisted on cardiac testing, chest x-rays, MRIs. Of the brain, the spine, to see if something was related. But nothing seemed out of the ordinary. I felt we were very thorough, but didn't come up with a solution, Dr. Hensley explained. But Cathy was growing sick and tired. Years of the mystery illness had affected Cathy's mental health. It impacted on her relationships, work, and most importantly, her quality of life. After 10 years of her flu-like symptoms, she decided that if no one could help her, she would. Help herself. So she decided to treat herself to a bathroom makeover. She had plans to create a sanctuary by remodeling the entire bathroom. She arranged contractors to take care of the job. But shortly after, they made a shocking discovery. The contractor's forehead crumpled with concern when he asked Cathy when her water heater had been installed. Cathy knew that it had been installed years before she had gotten sick, and Ashley must have been a little girl at the time. She thought hard and replied, maybe 10 years ago. The contractors were horrified. They had discovered that the furnace and water heater fitted incorrectly, were causing trace amounts of carbon monoxide to escape and leak into the house over an extended period of time. But isn't carbon monoxide poisonous? Carbon monoxide is colorless and odorless, invisible to the eye. This makes the gas a silent killer. When the body is exposed to it, the gas displaces oxygen in the blood, and this causes serious damage to the heart, brain, and vital organs, even A. Small exposure to CO can cause chest pains, fatigue, nausea, headaches, and vertigo. But prolonged exposure can have serious effects, including vomiting, muscle weakness, fainting, and confusion. Some cases of CO poisoning even result in death. But how had she been misdiagnosed again and again? After years of searching for answers from specialists and healthcare professionals, Cathy had lost hope. But now, Cathy's decade-long symptoms suddenly all made sense. The most unexpected visitors had finally given her an answer. I was shocked, she exclaimed. Cathy had been suffering for so long from an unexplained illness, and it had left her in the physical condition of an old woman. But how could she ever thank them enough? Over the years it kept getting worse and worse, Ashley explained. When she heard that finally there was proof of her mother's ailment, she was overjoyed. Now, Cathy would be able to function like a normal human being again. After years of her mother being bedbound, they would now be able to do all the things that they had missed out on like going shopping or going out for dinner. But could she ever forgive the doctors after all the years of neglect? Cathy hasn't felt this good in years. She got so much more than just a new bathroom from the contractors she got her life back. She's thrilled to have her body, mind, and spirit healed. I feel great, she said. I haven't been this happy and I can't tell how long. Cathy is well on her way to recovery after all the years of being exposed to poison, but there is still an element of concern to this story. Cathy wishes that she had pushed harder for a diagnosis. She had been called crazy, delusional and a hypochondriac for a decade because the tests were negative. She was prescribed the usual bed rest, exercise, or pills, but nothing helped. No one could give her the answers. But Cathy was right to trust her instincts. Even though she had to wait for 10 years for an answer, she is grateful. Cathy looks forward to her newfound energy and her new life, and she hopes that her story will raise awareness about the dangers of carbon monoxide.
