My wife is suffering for lower back pain problem for last 8 months. It was diagnosed as vit D deficiency & she took supplement. We also started with physiotherapy. However the pain is not reducing. She got similar pain 5 years before and with excercise it reduced but not this time. The MRI spine was done 5 years earlier & it showed no issue in spine. As of now we are continuing with physiotherapy & vit supplements. Doctors we visited are not able to tell us the exact issue. Could anyone here put some insight? We also met endocrinologist to check if any hormonal imbalance is causing the issue. He confirmed there is no connection.
