So i've been having this painful pain in my lower back for 2 months now and i finally wen't to a hospital .  the doctor ordered me a CT for me and it turns out i have a (L4 -L5 central and left paracentral disc bulge compressing thecal sac and the left nerve root).  The doctor said it's not serious enough to have a surgery and he just recommended me to lose weight (im 230pounds  5.8)  and some pain killers. please help.
