a few months ago i was lifting something heavy and work and i felt a pinch in my lower back, at the time i was going to physical therapy for upper back problems so i asked her to look at my lower back, the best she came up with was a herniated disc. i've been doing some research and none of the symptoms for a herniated disc sound like mine. my lower back feels like its squished and stuck... when i curve my back to stretch, everything above the lumbar part of my spine moves and my lower back just feels stuck, like somebody squised it and i can't pull it back to normal...my question is do you know what this is? why this is happening? and how i can fix it? i am currently on medical leave for another month and i don't want to go back to wrok only to make it worse. i already know how to properly lift heavy things and all that but none of the stretchs the physical therapist are helping
