i did my back in taking out a hedge in 1985 for my then father in law, didnt notice anything at the time but in the morning i couldnt sit down, could lie down, could stand up but couldnt sit on a chair, i was like that for a couple of months until it eased off, i have to be careful with it but under normal circumstances no problems, but i must NOT sleep on my back cos if i do thats it i'm in pain for days and i've got to take it easy,BUT sitting in a chair or taking to my bed is fatal..its got to be exercised-GENTLY. i agree with Kenneth an Osteo would do wonders for NR's back
Some people that prefer to be alone arent anti-social they just have no time for drama, stupidity and false people.
