Chiropractic adjustments, when done to the specific subluxation, and using a correct vector to restore the limited range of motion, very rarely hurt and almost immediately have a postive effect on a patient's symptoms. Of course, the severity of inflammation as well as muscle spasm may play a role in the resistance to an adjustment. This is why it is important that the adjustment be done with high velocity and a low amplitude.
Usually after an adjustment a patient may feel a warm sensation or tingly throughout their body. This is thought to be from increased endorphins being released and an increase in vascular activity post chiropractic manipulation.
When choosing a chiropractor it is important that he or she be specific in their approach and practice short lever adjustments.
