These symptoms are suggesting that you may be having a disc prolapse
. I would recommend you to get MRI of the spine to see if there is a disc protrusion
and if yes then how much . According to that you can plan . If it is in early stage then treatment will be physiotherapy
and muscle relaxant
and Pregabalin and Methylcobal.If it is in late stages then surgery is needed. Till that time, avoid bending forward and weight lifting.
