A young mother has died a week after visiting her GP with concerns over bruises on her body.

Health care assistant Sarah Armstrong, who has been described as "amazing", tragically suffered a stroke and died a week after she was given the heartbreaking news she had acute myeloid leukemia.

She was just 22 and is survived by a two-year-old daughter, report the Liverpool Echo.

Sarah, who worked at Aintree Hospital, visited the doctor when she noticed mysterious bruises on her body and was suffering with "flu-like symptoms".

Danielle Johnson, Sarah's childhood pal, said the mum-of-one thought she had flu and did not realise how serious things were.

Danielle said: "No one can believe it, everyone is in bits and shocked.

"Sarah was coming out in all these bruises and she had been telling me she couldn't explain where they were coming from.

"I said you need to get an appointment and go to the doctors.

"She went to the doctor and they said she would need to get a blood test. On the same day they called her to say 'you need to go to A&E, you're going to have to go now'."

Sarah was diagnosed with acute myeloid leukemia (AML)  a cancer of the myeloid line of blood cells, on January 24 and started chemotherapy treatment on January 29.

But she tragically died on February 1.

Despite the terrible diagnosis, Danielle said her friend was "very positive and strong" even when going though the gruelling treatment.

Danielle said of her friend: "She was just full of life. I just can't believe it, we were sitting there laughing the night before she died.

"They started the chemotherapy and she was doing amazing. She was always positive."

On February 1, Danielle had a message from Joel, Sarah's partner, asking her to call him right away Sarah had suffered a stroke and sadly died that evening, days into her treatment.

Paying tribute to her friend, Danielle said: "She was full of life. She was really positive, she did everything for everyone.

"She was always laughing and she always made everyone laugh. She was an amazing mum, she just always put everyone first."

A gofund me page has been set up to try and raise money for Sarah's funeral.
