Welcome to Healthcare magic forum,
Lower back pain
radiating to lower limbs
suggests inter vertebral lumbar disc prolapse
or bulge. The best way to diagnose is to get MRI
Precaution to take:
Avoid riding two wheeler.
Dont lift heavy weight.
Sleep on hard mattress and on ur back and side, dont sleep in ur abdomen since the muscles will get more strained.
Avoid sudden bending and turning.
Take hot fomentation daily twice.
Sit in a proper potion, dont hunch back when u sit.
U can wear LS belt while travelling.
Consult ortho specialist for further treatment.
Hope I have answered ur question,
