Plz help my father..
God bless us all.It began 24 years ago when my father shovelled dirt soil to cover unflattened land for half day.Meaning he bow his body(back)during that period,with the fact that he didn't do it on daily basis.That was not his job.The next morning, he couldn't wake up because of pain in his back. After seeing a neurologist,given prescribed medicine and went through 7 times out of 15 suggested body-pull therapies,he recovered.Ten years later,the backpain came back again due to tiredness of hard work repairing and lifting truck's machineries and transmission boxes and again healed.The third time, it happened eight years ago and he was hospitalized for a few days and recovered.Afterwards,my father was pretty active in hiking sports around two years.In normal daily lives,he was as active as if there were no problem ever with his back.Recently,the backpain came over and over again repeatedly from year 2008 until now.My father visited orthopaedic and orthopaedic surgeon to ask about his spine condition and they both said the spine condition is normal based on MRI scan result,there is no correlation between the complaint and the MRI scan.They recommended to go through ultrasound theraphy and shocked therapy.It worked well then,but not so now. My question is what is happening to my father's back??When the pain comes, sometimes it looks like a swollen sprain muscle,feels like his back being pushed forward suddenly.Lately, he prefers to lie down on the bed most of the time because he feels like his back burdened between the spine while sitting down or standing up.My father is 63 years of age.Any medical advices or alternatives,anyone? Thank You!
