What is the point of finding out what I'm allergic to when I see an allergist? Is there truth to the oral allergy treatments?

Avoid & Treat. Once you are aware of what you are allergic to specifically, you can avoid the things that are avoidable like pets, dust mite, and in some cases, mold. You can also be prescribed immunotherapy which is available in the form of allergy shots or allergy drops. The allergy drops are oral and are effective, although possibly a bit less effective than the shots. Both helpt o reduce your allergies.
