I'm very intrested in a future career in medicine that lets me treat all types of conditions and diseases. Recently I came to find a combined residency called med-peds. In this residency which usually takes only 4 years to finish, you end up with dual training as a Pediatrician and a Internal Medicine practitioner. How good is this program and if it something that will definatly not be a waste of time considered to family medicine which only takes 3 years to finish. Please do help, plus i was also wondering if u can actually practice two specialties at the same time in the same office or hospital.
