Hi there, not sure about all the allergies, but i also had pnemonia 3 times as a child. Our immune system is our only line of defense towards all these common occurances, but early childhood illnesses could always play a factor in auto-immune diseases. I had umbillicle hernia repair 6 months before I was dx'd with c/d. I for some odd reason used to blame the surgeon for giving me crohn's because I thought they might have used unsterile equipement when performing the surgery and ever since that surgery all food has a metallic taste to it also.. I also in the same boat that you are in also though. On friday i have an allergy scratch test and hope that goes well. I hope all goes well for you also. God bless..
