Yes you need to weigh up your options first, and an Atlas misalignment is a serious possibility, Have your cervical spine checked out first yeah! by a reputable Chiropractor, if that turns out to be your problem it will be substantially less costly to have rectified.
I have had mine adjusted and my bloodflow significantly improved, I only noticed as the upper veins in my hands increased, inherrited my Dads hands, didnt realise that they had gone until they came back so to speak. And Atlas misalignment is known to effect blood pressure. just google it you should get results show up.
Dont have a procedure that may not be neccessary
I do my own research, and find my own answers Its good to talk
