A mum lost a leg, went blind, was involved in a horror car crash and underwent a double organ transplant after an apparently-innocuous stumble over a step.

Remarkably, though, she insists she feels lucky because she is still alive and has finally found love.

Steffanie Wise, 35, was working in a brewery just over ten years ago when she stumbled over a step while pregnant, reports The Daily Mail.

Although she felt little pain, when it persisted Ms Wise, of Cornwall in the UK, visited a doctor where she was informed she had in fact broken her ankle.

After antibiotics, the ankle seemed to heal and all appeared well when she gave birth to her son Luke.

However, shortly after his birth the ankle wound became infected, and when she visited her doctor she collapsed in the surgery.

When she woke up was told her foot would have to be amputated.

"I know they had to resuscitate me a few times on the way to hospital," Ms Wise said.

"The first thing I remember in hospital was waking up after they had opened up my leg and washed out my ankle."

"That's when my surgeon told me there wasn’t much else I could do apart from have it amputated."

"I wanted to get rid of the pain and illness, I am quite matter of fact, it was either keep the foot and die or lose it and not die."

"I had no option, I had to be OK for my six-month-old son as at the time, I was on my own."

However, her health problems continued; her septicemia soon spread and caused Ms Wise to go blind.

Three years later, in 2006, she suffered kidney failure and caught the superbug MRSA after being treated for ulcerations.

And, after eventually being released from hospital, she was seriously injured in a horror car crash and shattered her thigh bones.

She said: "The engine was up on my knees and I split the side of my eye open. My back was badly bruised."

"I was pulled out of the car through the back door with my false leg mangled. I’d already had kidney failure so its function went down to 18 per cent."

Her treatment continued and she needed a metal plate fitted and a knee transplant on her good leg. Then last year she needed a double organ transplant on her kidney and pancreas.

Remarkably, though, Ms Wise considers herself lucky – especially after meeting fiancé Scott Poolton during her most recent hospital stay with the two soon to be married.

"I wasn’t looking for a relationship, I was still in hospital. I proposed to him in February, it was a leap year and we know we don’t want to be with anyone else."

"I think I have had quite a lot of good luck really, not bad luck. Considering everything I have come through and survived, I feel lucky."
