Excessive pain in back and hip. Normal.

Hi, I was having severe pain in my lower back and one day suddenly my left leg got numb and I couldn't lift it. I was admitted to hospital where after MRI scan it was mild disc diagnosed. But the pain remained constant. I was then after two weeks taken to hospital as my pain in the back reached till my hip and chest. Done with physio taking consultation from pain management but the pain keeps on increasing. Kindly see the reports and guide what can be done as I am unable to sit because of the pain.. I have consulted orthopedist, neurologist - almost 4-5 doctors, now they are saying that the reports show mild disc, which should not give such severe pain. Recent doctor has suggested me to take hip MRI also which has been normal. I am having so much pain that I am not able to go to office also and facing pain like an emergency sometimes, the pain is real however doctor is not understanding and saying the reports are normal.
