Mercyhealth allergists have the expertise to test you for allergies and intolerances, prescribe treatment and provide follow-up care.
The symptoms of allergies differ from person to person and different allergies can cause different symptoms from the very mild to the very severe: coughing, sneezing, itching, hives, pain, and swelling, just to name a few. Some people get headaches or nausea. Allergies can affect so many parts of your body too, from making your eyes water to your feet itch.
Because allergies manifest themselves in such different ways having an array of effects, there are many treatment options your allergist can prescribe that work better than over-the-counter remedies. There are prescription nasal sprays and eye drops too. Your physician may be able to help you with allergy shots and offer advice on avoiding your particular allergens.
