My Sciatica started early May 2016. I was getting better (could stand for 3-4 hrs, drive for 20-30 min and sit for an hr without any pain). But all of sudden, last week I wake up with same level of pain like in May and can't stand and sit more than ten minutes let alone driving. Did I re-herniate my disc? I haven't seen a surgeon yet but I am afraid that he/she will recommend to have it. How long should I wait before thinking about surgery?
