A man was left unable to move for more than a year after developing a painful disease that many people don’t even know exists.
Since he was 19, Dylan Conway has undergone nine different surgeries to treat his condition. At one point, his health deteriorated so much that he was confined to his bed for 14 months.
Dylan, who was serving as an infantry officer in the Australian army, first started experiencing unbearable back pain before realizing something was seriously wrong.
He described feeling “immense pressure” on his lower spine, assuming that after his first surgery, he’d recover and get back to his military training.
However, things didn’t go as planned. Dylan was diagnosed with pilonidal sinus disease, a condition that ended up taking over his life.

What is pilonidal sinus disease?
Breaking down what the disease actually is, the 27-year-old from Queensland, Australia, told ABC Science: “With pilonidal sinus disease, hair will fall into your pants and your buttocks rubbing against itself will actually implant hair into your body.”
“If you zoom in on a microscope with the hair, it looks similar to a screw. And eventually the friction from walking will end up embedding that hair follicle into your skin.”
Pilonidal sinus disease is notorious for coming back, often requiring repeated medical intervention. According to the National Institute of Health and Care Excellence (NICE), 78 percent of people with this condition experience at least one recurrence. Meanwhile, 19.2 percent go through two relapses, and 2.6 percent suffer from three or more.
After his first operation, he woke up to find a “huge chunk of flesh” had been removed from his lower back.
Recalling how exhausting and emotionally draining the repeated surgeries were, Dylan admitted: “Each time I would go in to have another surgery not knowing what I’d wake up to and see.”
“I went from being this really confident young man who was very confident in his body image to all of a sudden you can’t sit down, you can’t walk, I couldn’t socialise with my friends. I couldn’t see my family, couldn’t live life to be completely honest with you.”
