Hi,
How are you and your wife? How long have you been feeling these symptoms? It is indeed possible to have an allergy or infectious issue. Over-the-counter antihistamine medications may help provide relief with allergic symptoms. If it persists, you and your wife may need to have this evaluated further and to rule out environmental issues. Take care and do keep us posted.
Check ur home for mold....could be with all the rain that most of the country has been getting it could be a mold issue....
