The agony of a woman who can't walk because of her huge breasts... doctors have not been able to help

A woman has been left unable to walk without crutches due to a mystery condition that has caused her breasts to grow uncontrollably.

Lam Phrai Si Nuan, of Thailand, suffers from excruciating neck, shoulder and back pain because of her gigantic bosom.

Local reports claim the 46-year-old is forced to wear a heavy cloth tied behind her neck to support her breasts.

She first noticed her breasts getting bigger three years ago but said they started growing exponentially around nine months ago.

Mrs Lam Phrai, from a village in Phitsanulok province, claims doctors have been unable to diagnose or treat her.

Her left breast grew first for four to five months, according to local reports, then the right one grew afterwards.

But medics based at Phutthachinarat Hospital have ruled out cancerous tumours.

She is scheduled for a thorough medical exam on July 19 - but fears she won't be able to pick up the bill as her and her husband are both unemployed.

Mrs Lam Phrai is now appealing to the public for financial support.
