Hi, Thanks for your query. 
After going through your query I came to know that you are suffering from chronic 
backache. It may be due to vitamin and trace element deficiencies specially vitamin D and vitamin B 12. You need to done 
MRI to rule out other causes.
Back exercises, neurotropics such as mecobalamine and analgesics (
DICLOFENAC 100 MG SLOW RELEASE TABLETS) give relief. 
Sometimes vitamin D deficiency can aggravate this so serum vitamin D test is advised if it is low than vitamin D supplementation will be required. 
Avoid long continuous standing. 
Sit in a straight posture. Eat milk, fruits and green leafy vegetables daily.
You can discuss with your treating Doctor about it. I do hope that you have found something helpful and I will be glad to answer any further query. Take care.
