Hello, few months back i think i was lifting heavy weight in gym doing sitting shoulder press and i felt pain in lower lower back. Due to that i left gym and after that I feel that pain every now and then. Mostly while bending down. About shoulder pain it is probably due to the long hours sitting in front of a computer on a chair. My main question here is.. Do i have muscular pain in lower back or spinal pain? Should i go for physiotherapy or get xray done? Is this something related to survical? Please suggest treatment accordingly I hope to go to gym in Future.
