I had a real bad experience after my chiro visit about a year ago and I would never go to one again. Reading the article just gives me goose bumps, reminding me of what I went through after that visit, getting all dizzy and light headed, and then looking up on the internet what it could be and finding all over the web that dizziness after the neck adjustment can be a sign of stroke and it can happen to completely healthy people. I was not feeling well for days, and living in such a terrifying fear that I may be having a stroke for some time afterwards (it can happen even days or weeks after). I was mad that they didn't warn me that a stroke is a possibility, even though rare, but it's there. And she didn't handle it well after I called her to tell her what was happening to me. I am just thankful I didn't have any consequences.
Also, chiros are trained to keep you coming back indefinitely.
