Suggest Treatment For "L4-5 Left Paracentral Posterior Disc Bulge"

I am 25 years old male.3 months back i fell back while running.Pain occurs in the right buttock,numbness also occurs.Intensity of pain depends on the strain undergone.Sometimes pain is like some one is injecting in that part.With extreme strain i get pain in left ankle and right knee.Pain and numbness occurs in left buttock also but intensity is very less when compared with the symptoms in right side.My MRI scan suggests"L4-L5 left paracentral posterior disc bulge.L5-S1 diffuse circumferential disc bulge is seen with thecal CSF identation"
