I just had a weird experience with one I was going to - she adjusted me fine, but then she started doing some other weird thing where she is manipulating my feet and counting and asking me to say I am deserving of divine health.

Geez, just adjust me already.

Anyway, long story short I do want to find a new chiropractor who WILL adjust my back (because the one time she actually did it I got relief from pain I have been having for the last year that no medical doctor or medicine could give me relief from) but she said she doesn't do adjustments regularly and practices this other hocus pocus instead.
That "Hocus Pocus" is called Kinesiology and it's a powerful tool that does work if you'll just be open to it. For two years my daughter's life was a nightmare. She developed one allergy after another, peanuts, red dye, sunflower , all of her asthma medicine, eventually it became a new allergy every week. It went from reacting if she injested it, to if she came in physical contact and eventually she couldn't even be in the same room with the items. Two different peds, three allergy specialists and no one could give me an answer much less do anything to control it. My daughter was on her way to living in a glass bubble.
About 6 weeks ago I started seeing a new chiro due to a car accident. At that point my daughter had had an outbreak of hives and whelts everyday for 10 days straight. So I asked her if she had any idea what could be causing it and if she thought she could help. She started treating my daughter - without even charging me - because her case was so serious.
For the first time in 2 years my daughters allergic reactions
have reversed. She's no longer allergic to half the things she was before. And her reactions have gone from hives and whelts to merely itching. I can't even begin to describe the changes in my daughter. She's becoming healthier physically and emotionally. This Dr has done in 6 weeks what no other dr could do in two years. And it's all due to adjustments and Kinesiology.
I'm sorry to go all off-topic rant. But I think it's important that people see both sides of what you regard as "hocus pocus"
OP Speaking as a chiro patient and a massage therapist it sounds to me like the pain you're experiencing is a result of you tightening up. But that doesn't let the chiro off the hook. They should have prepared you better for the adjustment. Explaining how it would feel, massaging you to loosen you up and even using distractions.
My chiro often distracts me by telling me something random like "wiggle your toe!" and the adjustment is over before I realize it or
tense up. I have had some adjustments that were painful. Particularly in recovering from the car wreck. BUT typically it's been a strange combination of pain immediately followed by a sense of relief and release. With one really major adjustment I went from yelling out to laughing uncontrollabley. It was weird but it felt amazing.
I'd either talk to the dr and explain what happened and your concerns or try to find another dr. But don't give up chiropractic med really works.
