The last couple of physicals I have done I’ve gone to my regular doctor for everything but the eyes and had my eye doctor fill out relevant sections. Just made sure to have both set of contact information and signatures etc. the cg has accepted it both times.
I just finished my renewal and went to my family doctor for everything, even my eyes, she simply put down my vision corrected and non-corrected. If you don’t have any health issues you shouldn’t have any problems.
Type in your nearest city and the words DOT Physical. Certain places specialize in it. Call and make an appointment for a faster exam, if not you could be in there 2-3 hours.
