I RECENTLY HAD A LUMBAR DISCECTOMY 1 MTH AGO DUE TO 4MTHS OF CONSTANT SCIATIC NERVE PAIN AND AFTER SURGERY?

I FELT WONDERFUL FOR ABOUT 4 DAYS AND THEN MY PAIN CONTINUED. I WAS TOLD THAT I HAD 2 HERNIATED DISC AND THE DR WAS 99% SURE IT WAS THE LOWER DISC. IS THIS MUSCLE SPASMS OR WAS THE WRONG DISC???
