Why does distratcion pain start weeks later?

[Michelle]

I'm hoping maybe PainDoc can help answer this for me. I've heard people mention getting distraction pain post ADR placement by a couple of weeks. If the nerves are irritated by the increase in the disc height, why doesn't it start immediately after surgery? Also, will it help me that I've had 2 laminectomies at the same level as my ADR-as I understand it, they widen out the passage for the nerve through the bone? Thanks for giving your time to us spineys!!!!
