A:  First of all, unless they are a trained chiropractor, it would be impossible  for someone to "twist your neck and back the way chiropractors do." It takes  years of training for a doctor to learn the fine arts of manipulating and  adjusting the human body. 
			                Secondly, chiropractic is recognized world wide as  one of the safest non-invasive and drug-free treatments for neuromuscular  problems.
		                  Third,  while no medical procedure is 100% safe for 100% of patients, risks from  chiropractic treatment is almost unheard of. Of all complaints about treatment  by a Chiropractor, the mild soreness associated with spinal adjustment are by  far the most common. Interestingly, these aches are usually very short lived  and are gone within a day. Fourth, there are far greater risks in treating  musculoskeletal problems with prescription or over-the-counter (OTC)  anti-inflammatories than with chiropractic. The American Journal of  Gastroenterology has reported that about 33% of hospital stays and deaths that  are connected to gastrointestinal bleeding are  attributable to the use of aspirin and painkillers like ibuprofen. And finally,  some patients worry about the effects of cervical manipulation. (Cervical  manipulations is often referred to as neck adjustment or "cracking the neck.")  There have been questions about whether this treatment can contribute to  certain kinds of strokes. But, as any MD can attest, these same strokes often  occur spontaneously. History shows that injures to the arteries due to cervical  manipulation occur in about one case out of every 5.85 billion adjustments.  However, prescription medications claim the life of one out of every 450 cases  due to stroke.
