[144] Having found the compensable physical injury as cited above, including the objective physical signs elicited by various medical practitioners, I consider the following evidence of the plaintiff to be consistent with those findings.
[145] The plaintiff was born in January 1969 and is forty-six years of age. He attended Swinburne Technical College up to Year 8 and left when he was fourteen years old. Thereafter, he worked in a number of physical manual jobs.
[146] During the approximate seven years he worked with the defendant, the plaintiff worked as a full-time machine operator and would drive machinery over uneven ground involving a lot of vibrations and rocking. Approximately 40 per cent of his work was labouring duties. This involved heavy lifting and twisting and turning on uneven ground and manoeuvring weights such as pumps weighing up to 50 kilograms. He also worked eight hours a day from Monday to Friday, plus two hours of overtime every day and also six hours of overtime on Saturday.
[147] Lower back pain slowly developed over a one-year period from about 2011 to 2012. He also started getting pain in the back of his right leg as far as the knee.
[148] On 29 October 2012, the plaintiff was driving over uneven ground involving a lot of rocking and movement back and forth. He developed worse lower back pain and stopped working at about 10.30am. He has not worked since that time.
[149] Treatment has consisted of visits to his general practitioner, physiotherapy and hydrotherapy. He has also had epidural injections both from his general practitioner and from his treating neurosurgeon, Mr Craig Timms.
[150] The plaintiff complains of constant low-back pain which radiates down his back into the back of his right leg as far as his knee and sometimes down to the calf. The symptoms of sciatica happen at least once a day and sometimes the pain goes into his left buttock.
[151] The lower back pain gets worse if he bends or twists or does some forceful pushing or pulling.
[152] The plaintiff has difficulty sleeping and he gets up several times at night because of lower back and right leg pain. He also takes short naps through the day because of fatigue.
[153] At the time of swearing his first affidavit on 11 June 2014, the plaintiff was seeing his general practitioner once every two weeks and taking medication such as OxyContin, Endone, Tramal and Valium to relax his back muscles. At this time, he swears that he struggles with the housework as his wife suffers from carpal tunnel syndrome. He states that he can do the vacuuming and mopping although it hurts a lot. He has to take breaks and have rests.
[154] The plaintiff complains that his back pain is worse when he is straining on the toilet.
[155] Activities such as fishing with his friends or recreation on his jet ski are curtailed. On this occasion, the plaintiff swears that a few minutes on his jet ski became too painful for his back and he had to cease.
[156] The plaintiff further swears that he wears thongs or "crocs" so that he can avoid putting on or taking off his shoes.
[157] Regular attendance at the North Melbourne Football Club home games has been reduced to once or twice a year.
[158] The plaintiff states that sexual activity hardly happens anymore:
"When it does it's really painful, so now I just don't bother."
[159] In the ultimate paragraph of his first affidavit, the plaintiff swears:
"... Because of my work injury, I feel like my life has been robbed. I feel like my livelihood has been taken away from me and I am depressed because of it. I also had to sell my investment property for financial reasons and this was really difficult to do. I feel like all the work that I have done up until now has been lost."
[160] In his second affidavit sworn 10 February 2015, the plaintiff swore that he felt that his lower back and right leg pain had become a little worse. He stated he got sciatica pain down his right leg at least once a day and sometimes it is there for most of the time.
[161] The plaintiff further swore that he no longer took Endone and now takes one to two tablets of OxyContin a week. He stated he took two tablets of Tramal most days and he takes about two to four tablets of Valium nearly every day in order to help relax his back muscles. He has also now been prescribed Pristiq once a day for depression.
[162] The plaintiff further swore that he has gone fishing "about two times" since the injury. He swore:
"... On these trips, I remember going out a couple of times on the boat. With my back pain, I found it more difficult getting in and out of the boat and with the fishing as well."
[163] Further, in the past the plaintiff used to collect his own firewood by chain sawing trees, splitting wood and chopping same with an axe. He stated he used to obtain about 4 or 5 tonne per year. He now buys about 2 tonne for the year as he is unable to perform this task.
[164] The plaintiff also swears he finds it difficult to exercise his dog, Banjo, because of his lower back pain.
[165] On balance, I find that the consequences referred to above, particularly the constant back pain, the need for ongoing medication, the loss of sleep and the severe interference with his chosen occupation, are all consistent with the diagnoses that I have found to exist above. In all the circumstances, I consider that these consequences, when judged by a comparison with other cases in the range of possible impairments or losses of a body function, are permanent, in the sense that they are likely to persist into the foreseeable future and they can fairly be described as being "more than significant or marked" and as being "at least very considerable".
[166] Several medico-legal examiners have referred to the need for the plaintiff to attend a pain management specialist to try to get his use of narcotics and other substances under control. I will deal with this aspect of the evidence more fully in the economic loss category but suffice to say that I accept that even if the plaintiff attended such pain management, the consequences would still be "serious" as described.
