I have a mold alergy. I get itchy red eyes and a runny nose.
I don't have any allergies but I've always really been interested in how allergies work.
Well to that end, allergies seem to be caused by hypersensitivity of the immune system.
That does make sense, but what exactly causes this hypersensitivity?
I don't know for sure, but a food allegy for example is thought of as an abnormal immune response to food. This implies that it is a pathological condition.
