IgE surplus; Is having an abnormal consistency of mucus an AI disorder

Hi my name is David Ryan, I have had an abnormally high amount of IgE in my blood since a mold exposure from a basement in law apartment almost 4 years ago. The mucus build up in the form of post nasal drip has caused me to cough for years. Immediately after the exposure I was coughing every 20 seconds or so for about 2 years. Now I’m having issues with the consistency of my mucus. It is now very thick, sticky, elastic, and very dry. I’ve been waking up with my uvula sticking to the back of my throat at night. I constantly feel like I need to swallow from this post nasal drip feeling.

I had seen 3 different allergists, an ENT, a gastroenterologist, an environmental pulmonologist, and my primary care handfuls of times. I’m headed to see a different ENT in a week.

The best advice that I was given was from the environmental pulmonologist. He had said that mold exposure causes your body to create IgE or T helper immune response cells that release histamine like an allergic response. He said the cells could take 2 or more years to die off naturally without continued exposure to allergens. He had advised to take antihistamines and after doing endless amounts of research and review of others symptoms and treatments, the only medicine I could find to help was antihistamines. I had been taking antihistamines everyday for almost four years which did help the cough a lot at the time.

Now I’m worried that whatever reaction my body has had is evolving into something worse. Whereas the mucus in the back of my throat has been literally getting dry and oddly very sticky. I can’t relieve the constant feeling of needing to swallow because the mucus sticks.

I’m also worried that maybe the exposure could have caused a genetic mutation that could carry down to our children. We have a toddler now that is 2 and since she was born I have thought that she has a sticky type of mucus. At times I swear I can hear her popping a mucus bubble in the back of her throat as she tries to breathe. Baby Nasal spray has helped her sleep more comfortably we have found. She also mouth breathes a lot. I don’t now if that’s just normal for kids though. We’re taking her to her pediatrician also this week to ask these questions

Any advice or knowledge would be appreciated thanks
