Ive had back pain for 40 days.  MRI shows disc protusion L3, L4 with no nerve involvement, L5 S1 disc protusion with minimal displaced nerve root.  I have severe low back pain when sitting and driving.  Minimal leg/hip pain.  My question is about my thigh shaking when I walk down stairs, feels weak like it will give out, is this related to disc problem?
Hi, It seems that you might have stiff back due to osteoarthritis changes in your lumbosacral vertebrae giving problem of backache and problem while Chat Doctor. Go for physiotherapy daily and regularly. Do back extension exercise. Use hard bed for sleeping. Ok and take care.
