welcome to HCM,
as per the details u have been submitted, it seems that u are having chronic LBA with disc protrusion
or herniation leading to compression of your nerve
roots..i.e called RADICULOPATHY
..thats why you are experiencing numness and burning pain into your leg..
so before going to steriod
shots from a physical medicine specialist i advise you to a ORTHOPEDICIAN/SPINAL SURGEON and get done the following tests
1. STRAIGHT LEG RAISING TESTS AND PHYSICAL EXAMINATION , IT WILL BE DONE BY A ORTHOPEDIC DOCTOR
2. GET DONE MRI OF YOUR LS-SPINE
AFTER AN MRI OF LS -SPINE YOU WILL BE TREATED ACCORDINGLY..
90% OF DISC PROBLEMS CAN BE CURED BY GIVING REST TO LS SPINE BY LS SPINE BELT AND PHYSIOTHERAPY
HOPE THIS WILL HELP U A LOT, IF U NEED ANY FURTHER INFO...GET BACK TO ME...
