The NHS has apologised after a 26-year-old woman died following a misdiagnosis at a Nottingham NHS walk-in centre.
Rebecca Cain, 26, from Radford in Nottingham, died in June from deep vein thrombosis two days after visiting the centre with a pain in her leg.
An inquest was told the staff said it was muscle pain and had relied too much on a computer diagnosis system.
NHS Nottingham spokesman apologised and said improvements have been made.
Mrs Cain's husband Gareth said his wife told him she had been "fobbed off".
He said his wife had diagnosed her own condition as deep vein thrombosis on the computer using the NHS "symptom checker".
"She told me the nurse had ignored her… that she had been fobbed off. There was a chance there to potentially save her life," he said.
She died in North Yorkshire while they were visiting friends, two days after the visit to the NHS centre.
"This could have been prevented. This didn't have to happen - there was a chance to save her if people had listened to her," Mr Cain said.
The NHS said it had retrained staff following Mrs Cain's death.
Lyn Bacon of CitiHealth NHS Nottingham said: "Following the death of Mrs Cain we immediately arranged for an independent investigation into the quality of care and treatment that we had provided for her at the walk-in centre and into whether there were any wider issues that we needed to address."
She said the trust had introduced a series of "master class" training events for staff led by the medical director following the investigation.
