Sorry if this is in the wrong place, not sure where else to put it. Something has been puzzling me for a few years, I developed Pericarditis which is now recurrent on and off about 4-5 years ago. Ever since then, I have not had a bout of the Common Cold. If someone close to me has the Common Cold, I don't get it. Although, it seems to inflame my Pericardium, which sets off my Pericarditis for a day or two. Everyone around me can have the cold and will become infected, partner, parents, siblings - especially at this time of year have all come down with the Common Cold and became ill, but not me? I am not sure why really, but I have done some research and been led to believe, once the virus enters my system, my antibodies identify it instantly and carry it off to the Pericardium, where it is destroyed, hence why my Pericarditis flares up and my Heart Sac inflames. I do have other immune issues too, like Geographical Tongue, which is present every day. I have tried to look at some studies, but keep coming up trumps! I'm thinking of doing one of those research programs where they infect you with a cold virus to study it, and see if I actually do get the cold. Anyone offer an insight ? Again - apologies if this is in the wrong place.
