I whent to the Marine recruiters?

A few months ago I whent to the recruiting station and told them my medical history. I never whent to MEPs but she put it on her computer or what ever and I whent to another Marine recruiter and he could see it. If I was to go over to the Air Force and talk to them would they be able to see I talked to the Marines first. And how long would my info be in there system. I never gave them my SSN of my knowledge and I never whent to MEPs. If I whent to the Air Force and talked to them in a few years after college and whent to MEPs would they see anything? The question is would the information I gave her drop from the system from prolonged time.
