"I Tried Chiropractic And It Didn't Work"
Like you, I've had less-than-optimal experiences with people in a number of professions including CPA's, dentists, medical doctors and plumbers to name a few. However, when I had a bad dentist I didn't say, "Forget the dentist." I just found a new dentist who provided the level of care I expected. If you have a bad auto mechanic you don't just let your car sit in your garage and start walking. You find a better mechanic.
The two most common reasons for people to have a poor experience with a chiropractor are 1) the chiropractor's skills were not good or 2) the chiropractor didn't make sure you got the right care for your condition.
For problem #1: You simply need to upgrade to a better chiropractor. Being a chiropractor is much like being a surgeon. You must have a high degree of skill and dexterity to do it well. Being adjusted should not be painful or traumatic. A skilled adjuster can correct the spine with total comfort to the patient.
It's also possible you went to someone who did not even give you a proper chiropractic assessment and then ran you through a series of physiotherapy and "fluff" treatments and popped your spine a few times. The major subluxation(s) of your spine may not have even been identified. You may have never gotten real chiropractic.
"Many of life's failures are people who did not realize how close they were to success when they gave up."
~ Thomas A. Edison [1847 - 1931]
For problem #2: When a medical doctor prescribes a particular medication and the patient decides to take half the recommended dose then the medication is probably not going to work. It's not that the drug doesn't "work." It's that the patient didn't take the required dose. Chiropractic requires both specificity as well as a certain frequency - a certain dosage - in order to produce change. If you decide to access care based on how you're feeling from day to day then chiropractic will not "work" for you. But it's not chiropractic's fault when you walk out after one or two visits and say, "Hmmm, do I feel better yet?" Imagine a cancer patient on chemotherapy after a couple of sessions saying, "Wow, I feel like crap. I'm gonna quit this stuff." If your chiropractor says, "Just come back when you hurt," your chiropractor is an idiot. You've got to be led by a larger understanding of what is at stake and what you are trying to accomplish.
What is at stake to your health with Vertebral Subluxation and the resulting nerve interference? Spinal subluxation interferes with the flow of the controlling nerve impulses to your body. That interference leads to dysfunction. And dysfunction always precedes disease. Subluxation makes the body vulnerable to illness, injury and disease. For example, a specific subluxation in the region of the thoracic spine affecting nerves to the stomach can lead to digestive problems, acid reflux and any other number of problems. Antacids might help the symptoms, but no human being has ever truly had an "antacid deficiency." There's not such thing. This is not treating the cause. Correcting the subluxation is correcting the cause.
