Back not loosening

Hey y’all I posted before about how I injured my back somehow at work. All I was prescribed was a muscle relaxer (isn’t helping) and told to take aleve (also does not help). I’m under workman’s comp and have spoken to my case manager multiple times about how much pain I’m in and how while I can do my job (I work as a tech at a hospital) it just hurts really bad to do so. Like I was on light duty but they put me on the floor Thursday. I was sore all day, the pain was even worse yesterday to the point where it was radiating to my hip and I could barely walk. Today I’ve been fine due to being able to rest most of the day but anytime I’ve gotten up to do anything like laundry or tending to my pets, I’ve felt the soreness in my back. I have gone to physical therapy and have been doing the stretches but I end up hurting pretty bad after. I have quite a bit of tender spots in my back but massages seem to irritate my back even more. I was told at PT that my back is super tight but I’m not sure what else I can do to help get some relief. I’m just tired of talking to all these different doctors and my case manager and getting blown off
