When treating allergic reactions, consider the possibility of a heavy metal overload and ask your doctor to test you. The diagnosis of a heavy metal overload requires observation of symptoms, obtaining a  history of potential exposure, and the results of laboratory tests such as hair, blood and urinalysis.

You may find it is not your allergies; you might be carrying a heavy metal body burden. This could happen many different ways and it could be exposure to toxic heavy metals.

Acute toxicity is usually from a sudden or unexpected exposure to a high level of the heavy metal (from careless handling, inadequate safety precautions, or an accidental spill or release of toxic material often in a laboratory, industrial or transportation setting).

Chronic toxicity results from repeated or continous exposure either in the home or workplace, leading to an accumulation of the toxic substance in the body (contaminated food, air, water or dustl living near a hazardous waste site; manternal transfer in the womb;or from participating in hobbies that use lead paint or solder).

Here is where the allergies come in. Symptoms of chronic toxity are often similar to symptoms of allergic reactions such as sinus problems, migraine headaches, itchy or flaky skin, eczema, dermatitis, psoriasis,acne, itchy ears, sore or itchy eyes, mouth ulcers,nausea, fatigue and many more.  These symtoms could be a sign of chronic heavy metal poisoning and possibly a condtion much more severe than simple allergies. Unfortunately, it's impossible to recognize if you aren't tested and don't know to ask.
