Most mornings Frederick Bor wakes up screaming, in so much nerve pain from a horrific car accident that he wishes he was dead.

The Perth father is frequently rushed to hospital when the agony becomes too much, but doctors refuse to replace a faulty morphine pump that allowed him to live largely pain-free for a decade.

'The pain is like knives stabbing and twisting in my neck. I'm scared of going to sleep, laying down hurts and waking up is worse,' he told Daily Mail Australia.

'If I knew this was going to happen I would never have gotten married and had children, I would have refused the treatment and let myself die.'

The father-of-three attempted suicide three times until he got the pump, but when it was upgraded to a new model in 2014 it soon became faulty and his pain returned.

For four years doctors have refused to replace it despite the manufacturer offering it to the 49-year-old for free.

'I feel so guilty I am doing this to [my family], they don't deserve it. If I was single I would have departed this world already,' he said.

'I hear my daughter crying as the ambulance takes me to hospital at least once a week. I hear her pray at night asking God to please fix her daddy.'

Mr Bor's ordeal began with a car accident in 1987 where a tyre broke causing him to lose control of his 4WD and roll down an embankment on to its roof.

'When I came to, I was hanging upside down and I heard fuel running out and battery acid smell so I was very scared and didn't know how long I was upside down,' he said.

'I was scared of a fire and no other cars were in the area so I hit the seat belt release button and landed on my head, twisting my neck severely and I was lucky not to break it.'

Then only 19, Mr Bor was treated at an under-resourced hospital in Manjimup, in WA's South West, but never fully recovered.

He managed his pain and worked full time until 1994 when his condition worsened as scar tissue and the damaged bones in his neck began pinching nerves.

Numerous pain medications and surgeries failed to help and by 2003 he was confined to a wheelchair taking dozens of pills a day.

Mr Bor made three suicide attempts then stopped eating regularly and seeking help for numerous complications in the hope he would die.

'In three months I gained 30kg in fluid, tearing skin in certain places and even losing my big toenails from the swelling. My liver and kidneys were shutting down and I was at peace with it,' he said.

Finally, friends and family convinced him to have the morphine pump installed, which gave him regular doses of painkillers that allowed him to live with just the occasional paracetamol.

Mr Bor started working again and met Lyn, who he married two years later and in 2010 their daughter was born, joining Lyn's two older children.

'The pump turned me from suffering a horrible life not worth living to a life worth living - it was a second chance,' he said.

'Life was good, I still had pain all the time but I could live with it. I would hurt myself sometimes overdoing it but I recovered fast.'

By 2013 the pump reached its use-by date and was upgraded to a new version, the Medtronic SynchroMed II.

However, it soon began malfunctioning, giving Mr Bor overdoses followed by horrible withdrawals, or not delivering any medication at all.

He discovered the product had been recalled by the U.S. Food and Drug Administration in 2011 and blamed for 14 deaths.

'I'm scared of going to sleep. Laying down hurts and waking up is worse,' he said.

'Some nights the pain starts before I sleep. They are the worst nights, I take a cocktail of medication and pass out sitting up as laying down hurts too much.

'I'll fall asleep sitting up in front of the TV as watching movies takes the mind away from some of the pain. I'll wake up usually about 4am and take my morning medication and go to bed and cuddle my wife.

'When it gets beyond coping I go to the hospital but half the time a ambulance is called they have to strap me down as I cannot control my body as the pain is so bad.'

Ms Bor filmed her husband waking up in bed screaming and crying in pain while she tried in vain to comfort him, and another time when he was in hospital.

'My wife and I have a amazing relationship, our love is amazing. I have a loving family and a great life but living in this much pain is too hard,' Mr Bor said.

Mr Bor asked for the pump to be replaced but his pain physician, Roger Goucke, said the WA Health Service no longer used it for chronic pain patients.

Instead, his pump was filled with saline and he was prescribed a cocktail of tablets and Fentanyl patches which he said barely takes the edge off.

Doctors tried to install a cervical spine neuromodulation device that would manage his pain by sending small electric currents through his nerves.

However, after fives hours the surgery had to be abandoned as the damage to his spine was too severe and was not reattempted because of serious side effects in other patients.

Mr Bor again asked for the new pump to be installed but medical correspondence Dr Goucke was opposed to the treatment and thought it too risky.

'We, in general, no longer support intrathecal opiods for chronic non-cancer pain,' he wrote.

Dr Goucke was also sceptical that there was anything wrong with the pump, but in a recorded phone call a Medtronic representative said it appeared it was faulty.

The company offered to provide an updated version of the pump and its catheter for free, if Mr Bor could find surgeons to install it.

The North Metropolitan Health Service, which responded to questions from Daily Mail Australia on behalf of Dr Goucke, said the 'safety and wellbeing of patients is of paramount importance'.

'All efforts are made to ensure the appropriate care and treatment is provided at all times with all decisions being made in the best interests of the patient,' it said.

'As patient information is confidential; we are unable to provide specific treatment or medical records information.'

Mr Bor said he considered turning to the private sector or going overseas to replace the pump, but could not afford it with his disability support pension (pictured with his wife)

'I have a good life with a loving wife and loving kids but the pain is unbearable. I talked to them about dying but my wife said she would prefer me to lay in bed in pain than to lose me,' he said.

'But she knows when all options are finished and I have no option but to live like this, I cannot do it.'
