Moments after becoming a mother, Dusk Liney underwent a medical procedure that threw her back into "the darkest time" of her life.

The Victoria mum had sustained a third-degree tear during delivery and doctors stepped in to surgically repair it.

The procedure left her in "fight or flight" mode for days afterwards.

"I didn't know what was being done to my body and when I asked for that to be shared with me, I was told that wasn't possible," Liney told 9news.com.au.

"I don't think that [some doctors] realise the power dynamic that they're in and how [it can] mirror the experience of abuse."

Liney was sexually abused as a child, an experience she sadly shares with about 11 per cent of Australian women.
