Hi Kus-Knee, long time no see! Nice to see you posting again :) i have had problems with allergy due to the air pollution in China. I bought nose filters which are quite handy, and unlike a facial mask you dont really see that a person is wearing it. It can be good for any air allergens, including pollen and allergy towards animals.
being allergic to food is of course another issue completely and a very complicated one. Quite amazing that something like Quail eggs could make such a huge effect. But i am not surprised, often nature offers the solutions we need .
My cousin had many kind of allergy including egg and fish. He went to a chiropractor that made the problem go away completely. Also very unorthodox solution but as long as its not harmful i think it is worth a try.
Good to be back after a wild and hectic period. Thanks for your interesting points.
