Hi. As u said ur nearly whole back is painful. This is most probably related to Spine Problem. Is there any history of Trauma to ur back?. Or had u lifted heavy Objects before the Start of Pain? Neverthless, u need Xray (Even MRI if need) Of ur back in order to arrive at Firm Diagnosis. There might b DEGENERATIVE CHANGES or Some Vertebral (Spine problem such as Nerve Compression etc). So investigation is essential.
Morever 70% of Indian females Suffer from Vit D defiency n also have
Calcium Defiency . So U have to go for blood tests to assess Vit D n Calcium levels.
No need to worry. After Firm Diagnosis , Ayurvedic medicines Along with Oil massage etc treatment, U will b quite relieved of ur symptoms.
