It could be so many things, thyroid, allergies, auto immune diseases, but we aren't medical proffessionals (some of us are, but we can not give medical advice, per forum rules). We speak of personal experience, and as a person with thyroid problems, allergies, and auto immune diseases, I'd say keep seeing the doctor, and perhaps an endo? An endo dr covers my thyroid and diabetes treatment. Perhaps it can be something combined? Allergies and thyroid as an example. Sorry I can't be much help, this is better for a doctor.
