How long does an individual usually shadow for? I spoke with my family physician about a week ago and he said we could work something out to where I could shadow him for a week or two. I was hoping I could do it the duration of the summer, so just wondering if a week or two is the average time an individual shadows?

I was curious if MDs and DOs can do the same professions, for example can DOs be anesthesiologists, otolaryngologists, radiation oncologists...etc.? I know they can compete for the same residencies, but are there residencies for these professions just in the DO department also?
