When your sinuses become clogged, sinus headaches -- a feeling of deep pain and pressure above your nose and between your eyes -- can follow. Sinus headaches can range from annoying to severe, and they can sometimes be hard to treat.
But that’s not only because the underlying sinus problem can be hard to resolve. Sometimes, the problem is that people who think they have sinus headaches don’t really have them. Instead, they, or their doctors, mistake tension or migraine headaches for sinus headaches...
Skin testing is the most widely used and the most helpful in finding the cause of allergies. There are several different methods, but all involve exposing the skin to small amounts of various substances and observing the reactions over time.
Blood tests (RAST) generally identify IgE antibodies to specific antigens, or allergy triggers.
Other tests involve eliminating certain allergens from your environment and then re-introducing them to see if a reaction occurs.
People with a history of serious or anaphylactic reactions may be prescribed an auto-injector, sometimes called a bee-sting kit or EpiPen. This contains a premeasured dose of epinephrine. You carry this with you and inject yourself with medication immediately if you are exposed to a substance that causes a severe allergic reaction.
There is some evidence that breast-fed infants are less likely to have allergies than bottle-fed infants.
