Hello
Thanks for writing to HCM
Lower back ache may be due to many reasons.
You need proper clinical examination and investigations.
Besides abdomen visceral causes,
lumbar disc prolapse should be excluded.
You need investigations like routine hemogram,Random blood sugar(RBS),
Liver function test(LFT),Renal function test(RFT),Serum calcium and vitamin D level,
Ultrasound of abdomen,X-ray L/S Spine (AP/Lateral),
MRI L/S Spine.
MRI can exclude disc prolapse possibility.
Further investigations can be done if needed.
Proper treatment depend upon clinical findings and investigation reports.
Hope i have answered your query.
Take Care
