Doctor of osteopathy (DO). My first doctor as an adult was a DO and treated things like sinus infections with medication, but when I picked up a ladder and something popped in my back, he adjusted my spine and put it back into place and almost instantly it stopped hurting.
I worked with MDs for years and they said DO was considered a legit medical specialty, just non identical curriculum. Chiropractics was more a specialized physical therapy practice, also useful, if expectations are sensible.
I had a primary care provider who was a DO and she was a wizard, but sadly moved out of state.
