allergy to eggs?

Ok guys,,, if there is something I soooo miss eating in the whole wide world its eggs!!!!! I use to eat eggs my whole life,,, over easy, scrambled, fried egg sandwiches, boiled eggs, deviled eggs... I cant even write anymore about them I miss eating them so much!  Well about 8 years ago I had an egg and my stomach got so much pain,,,, I had to get on all fours on my bed and just roll and roll on the bed in such pain,  The pain lasted for about 4 or more hours,,followed by diarehea etc.  I just though ok,,, so about a week or more I had another one,,,same thing,  Then months past same thing,  Year later,,, it had to be the eggs.  So i wouldn't eat them anymore,  I had french toast about 2 years ago and i noticed just a little yellow from the egg on the outside of the french toast was on there,  I got the same unbearable stomach pain from it,,,just that little bit.  I can eat things with egg cooked in it but just cant' eat eggs,  I am not sure if its allergy or what,  Same thing with Bananas,,, haven't eaten them for years and thats another story I miss them so much!  Just the taste of a banana but oooohh I can't take the stomach pain and runs etc,  
I cant eat cashews, postashios (sp), and not sure about walnuts cuz with those I get that same pain except my lips will start to tingle and I start coughing immediatly after eating just one along with the stomach pain and runs,  But the egg thing really gets me upset,  I can still drink and eat other dairy products,,,So I don't know if this is an intollernce or allergy.  Also I am very sensitive to most antibiodics and medication,   I pass..
