I have studied your case with diligence.
At old age there can be degenerative wear of bones, muscles, ligament and facet joint arthritis
, due to deficiency of calcium, vitamin D, VIT B12.so supplements of these nutrients can relieve pain.Osteoporosis
may be associated leading to diffuse pain in back.
Check your bone strength with DEXA SCAN and you can start medication according to level of osteoporosis,
I will advise you to do MRI spine to see for any disc bulge or spinal canal
And also check your vit B12 and vit D3 level.
You need to start supplement of calcium with vitamin D, vit B12, and if osteoporosis is severe then bisphophonates can be started.
I will advise you to do regular physiotherapy
and exercises as my patients find much relief by these therapies.
You may consult physiotherapist for guidance. He may start TENS, or ultrasound
which is helpful in your case you need to take diet rich in calcium and vitamin D.
This can be due to menopouse.
