Does anyone here has approached them for services?

I have used a chiropractor in the past. I would advise not seeing one unless s/he is recommended by someone you trust. Range of ability can vary greatly. But I would really recommend a physical therapist. I have had pelvis out of alignment which was fixed in Pt. I would still be in a wheelchair without them. It amazes me how they can identify  a weak muscle and then figure out how to isolate it with the exercise to strengthen it. I had horrendous back spasms that I have not had in a year because of learning how to strengthen my core. I cannot say enough positive things about them. I've worked with 6 over the past 2 years .
I also prefer pt over chiropractor because I feel more in control and an active participant versus having someone adjust me-personal preference
