I have used the search function and I am aware that having flat feet alone is not a bar to entry. However, I was not aware I had flat feet until I was told in my Navy medical and when asked if they caused any problems I said no. Recently though I have been getting hamstring injuries from tight hamstrings, and I am starting to wonder if that is because I have flat feet. I have been considering going to the doctors but I am concerned if it turns out my flat feet are causing my hamstring tightness it could bar me from entry when I ring AFCO to update them on my medical status? Am I going to risk my entry to service by going to the doctors about my flat feet? Should I just ignore the problem for now?
