I had mine when I was three. My parents noticed first because when they looked at me closey my eyes were slightly unaligned, only slightly though. My doctor at the time dismissed it but three months later it was very obvious something was wrong. My eye could barely open and looked rather swolen. I dont recall if there was any tenderness or sensitivity.
I've never had nasal polyps, so Im not sure but maybe that could be what you have. Are these 'pimples', do they affect you're breathing thru the nose? Maybe you should ask your doc the next time, or someone else on here may be able to help!
