Is it safe for my chiropractor to use a vibrating massager on my lower back and buttocks during pregnancy? currently 18 weeks

Vibration : That depends on your pregnancy. Human nature is that people connect things that are not connected. Women sometimes have problems with their pregnancy unrelated to outside causes. While nonaggressive vibration is safe on the back and buttock during a normal pregnancy when a pregnancy goes poorly, the disappointment rarely allows people to accept that there was no outside reason.
