Suggest Treatment For Breathing Difficulty Due To Cranial Bone Fusion

Good morning. I am asking for some advice about someone I know. I am a Chiro and while googling some information to back up my textbooks I came upon this site. This is your area of expertise and was hoping to get an opinion. 45yr old female with a decrease in breathing ability due to cranial bone fusion because of birth trauma. She is hyper reactive to everything. She gets a IgE reaction and massive histamine release to most foods. The last reaction was due to sniffing into a plastic packet to see if it was clean or to be thrown away. The next thing she couldn t breath and broke out into hives. It took 10 cimetadines and gentle mobilization to restore normal breathing. She is under medical care. She is due for cranial Sx in 2 months to restore normal breathing. Question: The hyperactivity of the immune system. Could it be due to an enlarged Thymus?
