Greetings.
Is the pain aggravated by the posture and back movements? Was an ultrasound done for the kidney stones? Do you have bloating, nausea, loss of appetite, constipation/diarrhea? Are you on any medications? Any significant past medical or surgical illness?

Hello,
A pain related to the posture (coming and increasing on lying left side), would point towards musculoskeletal problems (muscles, ligaments, spine joints) then the visceral origin. The work up in your clinical manifestations are following;
1) MRI of the back
2) CT scan of the abdomen
3) A hormonal work up
This should give the insight for the cause. An orthopedist would be the specialist to consult initially.
Please feel free for your follow up questions.
