I hope this advice does not find you too late. I am actively involved in the AMA an attended a recent convention in Chicago and spoke with fellow medical students. I found everyone very aware of osteopathy and very accepting. You can practice in any speciality. For me I am looking at anesthesiology.
Medical school is extremely demanding, but it can be done with children.
If the answer is yes to all these questions then you should go. You could ask there for salaries. MomMD does not provide medical advice or information.
