Thank you so much for sharing! I hope you get your thorough investigation soon. I think this is the blood test they did on me. Interesting 90% is a lot. Is Cromolyn and Ketotifen similar? are this kinda like Benadryl?. I have so much inflammation on my nasal cavity my locals say it’s just allergies and gave me fluticasone. So maybe it would be a good idea for the biopsy in my case. I can’t enjoy BBQ anymore 😓 without itching sore and trembling throat like bolus.
