Does high allergy level serum ige and gerd can cause pharyngitis for 6 months and occasional blood mixed with mucus plus to much mucus production.

It's possible: An elevated IgE level is most commonly linked to allergies, whether environmental or otherwise. Environmental allergies could lead to pharyngitis, as that is a common allergy-related symptom. GERD can also cause a painful throat, due to chronic acid exposure. In either case, chronic damage can lead to the presence of blood and/or mucous. Of course large amounts of blood are abnormal.
