Is it normal that whenever i see earrings (in or not) i feel sick?

When I was a young child I used to eat Lego, especially the small little red and yellow 'buttons', simply because i was young and surrounded by Lego, in total i only think i ate a dozen or so over the years, however, as i passed through my teen years i started to notice that whenever i saw small bits of jewellery (such as stud earrings) i have a sudden icky feeling, i ignored this feeling for a long time by simply moving away from the earrings, however, now that i am older, it's about time that i started dating, however so far i have always freaked out when i see studs in their ears, this is really starting to get in the way of my dating life. And i would like to know if anyone else used to suffer from this, and possibly got over it, if they did i would appreciate any advice with it, also feel free to comment if you too have this problem.
