For those unaware, osteomyelitis is a life-threatening condition that causes inflammation or swelling in the bone.
It is caused by a type of bacteria found on the skin - the staphylococcus bacteria - and can spread the blood to other bones in your body.
If left untreated, the condition can lead to permanent damage and even death, with a one-in-five mortality rate
Nat continued to describe her harrowing ordeal and painful recovery process, detailing her experience of receiving a lumbar puncture - a painful procedure that sees a needle inserted directly inserted into the spinal canal.
"It was traumatic - I didn't know if I'd be able to walk again."
"It was a really defining moment in my life because I was 15 years old and old enough to think, "I don't know how I'm going to get out of this situation."
Thankfully, Nat is well today and recovered fully with no lasting spinal damage, but admits that it was still a difficult time after missing a term of school and taking some time to recover her full strength.
