Thank you for posting your query on ATD.
I have gone through your query and understand your concern .Likely cause of your back pain is weakness of muscle and bone. You can get your vitamin D level and if found low you can get its supplements (vitamin D3). Back exercises are useful. You can take calcium and multivitamins supplements. Further investigation will need MRI of lumbar spine. Hope your query get answered.
Wishing you a good health.
