“Systematic reviews of controlled clinical studies of treatments used by chiropractors have found no evidence that chiropractic manipulation is effective, with the possible exception of treatment for back pain.[8] A 2011 critical evaluation of 45 systematic reviews concluded that the data included in the study “fail[ed] to demonstrate convincingly that spinal manipulation is an effective intervention for any condition.”[10] Spinal manipulation may be cost-effective for sub-acute or chronic low back pain, but the results for acute low back pain were insufficient.[11] No compelling evidence exists to indicate that maintenance chiropractic care adequately prevents symptoms or diseases.[12]”
The thing is, this study is talking about “chiropractic manipulation” which is a very specific thing. (With that clicker thingy I think?) The thing is, chiropractors tend do do lots of different therapies, like stretching and massage. So you could go to a chiropractor who performs some kind of massage which is effective at temporary pain relief.
