Hi there,
for starters, have you been to a physician to have your back x-rayed? Have you been given any info. From an actual doctor?
I suspect there is a reason your back is feeling "kinked up" and that could be why your pain is relieved for only a short period of time. If you have a problem with your spine, all that adjusting can make it worse.
I am not a doctor but that is what I would tell you to do............
