Ajedrecísta, allergies are a consequence of a disregulated immune system, there are not easy solutions to them - there is not a "cure" for them, they are a chronic condition. By your posts, you are only beginning to be aware of it.

Allergy problems are also very individuallized (yours and mine probably will have some common areas but also very different ones). I could tell you what made my life better, but I think it would be better for you to

i) find a good doctor - don't look for someone who is an "allergist" (could be a GP who does allergies, these will probably treat only the symptoms) but an "immunologist". These are the best as they will try to treat the causes (albeit with limited tools)

ii) you will need to develop a sense of what causes the allergy process to you, and to avoid or circumvent these triggers. It is much more effective to do it than to revert the manifestations of the allergic reactions.

As all chronic conditions, you need to learn how to deal with it; from time to time it will weight harder on you, but your life will be easier the better you understand your condition. I don't know your age; if you are young and this is your first encounter with a chronic illness, the process can be disturbing, but I'm sure you will learn how to deal with it.

Good luck and Welcome to the team
