Discbulge post microdisce. Help?

I had microdiscectomy 2 years back at L5S1. Last few months started experiencing lower back pain and pain in buttock area and some numbness in left leg again. MRI says posterior central disc bulge with subanular interstitial tear and no neural impingement. spastic straightening of lumbar curve. osseus hemangioma at l5. degenerative changes at l5s1. I want to ask for treatment apart from medicines which I am taking anyways. Will physiotherapy help ? And if anyone can suggest someone I can go to who has had previous experience in such a case as this is hampering my everyday activity as I have to have bed rest and cannot sit for long duration. I go for walk daily and do some back strengthening which i was told after my surgery 2 years back. Thank you.
