May be you will benefit from a microdiscectomy if there is severe compression in the L4,L5 nerve
roots and chord.Only we will come to know what is to be done based on your MRI
findings. Consult your neurosurgeon and do the needed surgery if required.There will be good relief of your pain after the surgery and you can resume normal duties in a period of one month or even 2 weeks,though initial two months after the surgery you might need to wear lumbar braces just as supportive measure.Hope there is no weakness of any particular left or right lower limbs/legs.Lyrica
is usually prescribed along with physiotherapy
in the initial period because your symptoms have just recently started.There is one more modality of conservative treatment called epidural infusion of anesthetic(in spine area) in which some patients get benefited.
