I guess it depends on where you are and who you get, but I had my first one yesterday and it was fantastic! You can see some posts about it in the third trimester section. She asked me a lot of questions about the pain and other things related to my pregnancy, then she had me do some bending in different positions with her hands on different parts of my lower back and then she felt the front of my pelvis while I was laying down. This was all to find out which side was worse and how I was misaligned. She found that my left side was way out of line with my body (I KNEW I felt like my leg was longer- even before I was pregnant!). Because of this, she had me do a couple of movements (pushing my legs against her body in different positions) in order to get my pelvis realigned. I'll be honest, it was SORE... But afterwards it was fantastic. I was no longer limping and I got the best sleep last night. I feel really good today, too. My sacrum is still sore, but i have been sitting at a desk all day so that isn't a surprise. I have been given some exercises and if I stick to them there is a good chance my pelvis will stay where it is meant to be. If not, I can call and get it pushed back again. Ha... eww... I have another appointment 8 weeks from now but was told I could try to come sooner if I needed to. I wasn't given a support band or belt or anything. She said as long as I do the exercises I shouldn't need it because my muscles will do the same thing.
