I am looking for a doctor in NJ to follow up with: surgery done outside the U.S. Where can I go?

This is a question that you should have more carefully considered before you had surgery outside of the US. Most surgeons are not interested in doing the follow up care that another surgeon has already been paid to complete. Your best option is to ask the surgeon that completed your procedure what his/her follow up protocol is supposed to entail. You should be able to contact your surgeon and he/she should be providing you with the answers or resources to your questions.
