Talk to Orthopedic on Left Leg Pain

my father has pain in left leg from previous 5-7 months which got severe from last two months and he is unable to put weight on that leg. Initially pain used to move from tight till leg now its static at thigh. 1-First he went to arthopedic and he prescribed for MRI (Report is attached) he mentioned that it's disc prolaps and go for Surgery and he advised to consult neurosurgeon. 2-Dr neurosurgeon advised for therapy first. We did his therapy at home but got no useful results. Then we thought to switch doctor as he had severe pain in his leg. 3. Then we went to another neurosurgeon at CMH Rawalpindi, he asked for another MRI plus few other blood tests as well as bone scan. All tests reports are attached. He diagnosed with Bone TB and asked us to start TB treatment for 1year, which is continued since last month. Pain is still there and he can't put weight on left leg while walking. Here are all the tests reports along with Dr prescription.
