Dear patient Your mri of dorsalumber spine suggests disc bulge and tear with nerve compression that means disc has come out of its space and is compressing the nerve root which is responsible for sharp pain in legs.you are taking strict bed rest and pelvic traction that is a correct treatment. But how much relief is Ther from current treatment that u have not mentioned. If you have been on traction for a week and not getting relief then you should go for epidural steroid injection. It acts by reducing swelling and inflammation around nerve root And is a harmless opd procedure. You can visit pain specialist nearby you for same. And if you are getting better with traction continental for few more days and you wl get relief.
