hi,
thank-you for providing the brief history of you.
As per the history I understand that you are not undergoing sufficient
physical therapy session. I will say underground 2 days a week is for no sure going to help you at all. You need a minimum of 5 days a week of Physical therapy.
Also, by your x-ray report mentioned by you I feel I is work related issue and you need and
MRI for this.
I think this is more of a
spondylolisthesis of the L5 over S1 region , it's a mere speculation but with understanding the MRI study and comparing to clinical symptoms we can come closer to conclusion
Also, as you are a delivery boy, this conditon would have made some changes in the posture and lead to abnormality in the sacral region. Also it's totally a looking the mechanism of
injury is due to job profile.
Also I will advice you to undergo and MRI and also increase the number of your weekly physical therapy sessions for upto 12-16 weeks. As in my clinical practice most patients have work related injury like how you have now, and responds well to physical therapy when the proper kinematics of the spine and the injury is understood.
