Physio / Chiro is only going to stretch / manipulate lower back hip area to help mobilise so you may aswell try some of the stretches to see if this is going to alleviate the problem.
If it works you save some cash, if it doesn't go see someone.
You'll find that the Physio will prescribe said stretches as an on going management regime anyway...
Apart from seeing this sort of stuff everyday two fractured vertebrae and a year in a back brace gave me some first hand experience
