I have a pain in my lower back and cramps like on my left thigh some times when i sit i feel better but when i walks or stand for more than one hrs. then again pain in my lower back starts few months ago my MRI ( LUMBOSACRAL SPINE) showed as: Mild diffuse disc bulge with protrusion at L4-L5,Annular bulge at L5-S1,Predominatly Para-Posterio-Central(RT LT) resuling compression over the epidural SAC,Thecal SAC,Exiting nerve roots with maintained spinal canal dimension & neural formation stenosis at L4-S1 suggested mild prolapsed intervertebral disc with polyradiculopathy.Early Lumbar spondylosis changes. As per suggestion of Doctor(MCH.ORTHO) i am taking Zevanuron Capsule once a day since one month but there is little improvement in my lower back pain .I am 33 years old and my weight is 74 Kg and height is 5 2 . Should i continue ZEVANURON CAPSULE only or any other medicine ? Kindly suggest me about root cause of pain in lower back ,medicine ?,precausions etc .
