Anyway you could get a quick referral from your Doc. ( I assume GP) for a Pain Specialist?
If not you could always go to an urgent care, but I've heard some great things about Pain Specialists really coming up with comprehensive programs for similar situations. Are they thinking surgery might be necessary? Hope you feel better soon. I don't think think its childish at at all. I blew out my sciatica to the point I could barely walk and it almost hurt to talk. Its under control/barely noticeable with regular OTC pain meds and weight/band exercises. I can hardly image a crushed disc.
