When the immune system responds to a foreign substance in an abnormal way, it is classified as an allergy. When the body first contacts the substance, it will not cause any reactions, but the immune system will start to produce antibodies to it and subsequent contact will trigger more dramatic responses. Depending on the allergy, the response could be mild or very severe...
I also suffer from allergies to dust mites, dog dander--extremely, egg whites, red pepper, chilli powder, mold-which is in leaves this time of year, and others. My guess would be that it is just not dust mites.
My guess would be it is something else besides dust mites. Now that I am over 60, I have developed some kind of allergy to foods. Not really sure what exactly. Scratch tests don't reveal enough of what someone is allergic to.
I am presently taking an injection once every two weeks called Dupixent. (sp?) It helps some, but I still break out on my face. It turns red and I swell up like the Hulk. Then I am put on a steroids, which clears it up for about a month.
When I was young my mom would put me to bed with white socks on, so I wouldn't scratch my skin open.
Try keeping a food journal of what she eats, that might be helpful.
