That’s a fair point; everyone is entitled to their personal space. However, there are a few things to be said about this.
First, a chiropractor is a doctor. They’re licensed, and they spent roughly nine years in school to get their degree to practice. If you have any doubts at all about your chiropractor, just ask about their license.
Secondly, as with all doctor visits, communication is key. If at any point you’re uncomfortable, you can tell the chiropractor, and he’ll listen to you.
Third, an adjustment doesn’t always happen on a first visit, so you’ll have time to meet your doctor, build a rapport with them, and truly understand if their services can help you.
