An update about good chiropractor, big thanks to Blairbear and Djohn78! Dr. Hatch is the best! I met him 2 times before my departure. My back still sore at that time and I was a bit scared thinking of my 12 hours flight.
It was not bad at all, I felt uneasy but my back is totally okay during my whole trips. Dr. Hatch told me to come again to his office after my trip if I still feel uncomfortable.
I just got back here in The Woodlands 2 days ago and I don't feel anything, it just like I never have it! so my 2 trips to him just as great as it is!! Thanks again !
