I have an allergy that has never been discovered the cause for years?

Good Afternoon, I have an allergy that has never been discovered for about 8 years, but this allergy comes from nowhere and goes out of nowhere as well. I have taken too much hixizine, and it seems that it is no longer taking effect, I have hives and swellings. I have contracted a medical covenant to treat, but what I would like to know is if in those 30 days that I will wait to release the covenant, is there any risk of that allergy reaching a point that I can not control, and what can I do to reduce them without medicine Thankful.
Expert answer:

Besides praying, you may not be nervous either. Did you know that there are allergies triggered by emotional problems (who knows the cause is not there for your allergy that you are looking for). If you do not find your answer, seek a homeopath doctor, he may not give you the answer, but you will probably find a remedy to cure or improve your allergy.
