Forty-year-old mother Claire, had a hysterectomy - an operation where the womb is removed - 12 weeks ago.
The mother-of-one needed the surgery to relieve her "debilitating" endometriosis and adenomyosis.
The surgery cost Claire more than £10,000 with a private consultant - the same one she is on a three-year waiting list to see through the NHS.
"This was the last option, it was desperation," she says.
Claire, a librarian, struggled to get anyone to take her pain seriously during her teenage years. It wasn't until she was 22 that she received a diagnosis of severe endometriosis.
The diagnosis gave Claire, who had always been told her pains were related to an irritable bowel, hope. She recalls her mum being told by a doctor: "I think it's just IBS. Get her to suck on a Polo mint."
But the endometriosis diagnosis was just the beginning of a continuing battle for speedy NHS care.
"These [gynaecology] appointments are a lifeline for us," she says. "We are in so much pain but we know it's okay because in a few months we'll be seeing this consultant or doctor, and then when they cancel it is heart-breaking.
"Out of every month I was getting one good week and around that it was about managing the pain and the emotional effects of that."
Now Claire, who also suffers with premenstrual dysphoric disorder (PMDD), a period-related condition causing extreme distress, must weigh up how much to rely on costly private care as she continues her treatment.
"I know I'm in a privileged position to be able to have gone private," she says.
"The nurses were amazing, the aftercare was all followed up, they referred me to physio. But I need to continue with the NHS now because otherwise, where does the cost end?"
