Jessica, 13, has been diagnosed with hereditary scoliosis – a problem that previously affected her mother and grand-mother Jennifer.
The condition can cause severe disability, organ damage or even death if left untreated.
The teenager, from Burnley, Lancashire, is set for the surgery that will involve her ribs being reset, corrected and supported with a metal rod.
Her mother said: ‘When Jessica was diagnosed with the condition I just kept thinking it wasn’t fair. I had gone through it, so why her?
‘I just felt sick because it was history repeating itself, and I was reliving the worst time of my life as a teenager.
‘I only realised it was hereditary when I did research after having Jessica. When my mum got it, I knew then it really did run in families.
‘You would take a bullet for your child, so it was knowing I would be sitting with her and knowing what she was going through that upset me – I would have gone through it again for her, if I could.’
The beauty salon owner was 11 years old when she was first diagnosed with adolescent idiopathic scoliosis (AIS) and was fitted with a torso cast and endured countless physiotherapy sessions.
Recalling the pain she went through, the 36-year-old said: ‘I had to wear a hard, plastic body brace, which I wore 23 hours a day.
‘I was a very skinny teenager – so I had absolutely no confidence. It made me so body conscious.
‘I lost interest at school – at the time I thought to myself there was no point if I was going to end up in a wheelchair.’
The family are now trying to raise awareness of scoliosis, a condition which affects one in every 2000 people, and are appealing for donations to the British Scoliosis Research Foundation.
A spokesman for the Scoliosis Association UK said: ‘The cause of degenerative scoliosis can be attributed to weakening bones and other degenerative conditions; however, the cause of adolescent idiopathic scoliosis is unknown.
‘Although important research continues in this area, including into the genetic basis for AIS, there are no identifiable causes for this condition.’
