Young woman forced to leave her job because of debilitating pain from large breasts.

A young woman has been forced to rely on Centrelink payments after excruciating pain from her large breasts rendered her unable to work.

Sydney woman Nim Murphy says her 12HH breasts inflict so much physical pain she is often left motionless, unable to even roll over in bed.

The 27-year-old is currently awaiting breast reduction surgery but due to her lack of private health insurance, faces a waiting list in the public system that she says may take years.

Murphy told A Current Affair her breasts have made her feel as though she can’t progress in life until she receives the surgery.

“Everything feels like it’s on pause until I feel like it can happen,” she said.

Murphy left her job as a roadie when incidents of chronic pain left her not only unable to work but unable to function.

"About two and a half years ago I had to call in sick because I got out the front door and started vomiting in my front yard just from the pain and so I had to stop working," she said.

Murphy previously worked on tours for such big names as Taylor Swift and Slipknot - a job that is hugely physically demanding.

The young woman says that although she could take a job that is less labour intensive, she fears the occasions where the pain is too severe will mean she will be calling in sick too frequently.

This is further exacerbated by her neck injury called a reversal of the lordotic curvature - and although it isn't caused by her breasts, it is aggravated by their size.

Murphy revealed her breasts have caused her to become the target of ridicule and harassment by strangers.

"I've had total strangers, come up really close in my personal space, and say 'you've got big tits'," she said.

"It freaks me the hell out. I wind up hunched up - pull my coat around me."

The amount of criticism she faces has left her fearful and sometimes resenting leaving the house at all.

"I don't like going out in public," she said.

Specialist plastic surgeon Dr Dan Kennedy told A Current Affair that breast reductions were one of his most rewarding procedures.

"When people come back after their operations they say that they've had a dramatic relief of neck pain, back pain, shoulder pain," he said.

Murphy's story may sound extreme but there are many women who suffer pain as a result of their breasts and are unable to afford immediate surgery.

Procedures such as breast reductions can be cosmetic but they are often hugely relieving surgeries that truly assist a woman's quality of life.
