Hi - I have been having what I assumed were indoor allergies for a few years now. They developed suddenly (I'm 30) and I never had anything like this as a child. The strange thing is that I have no stuffy nose or other nasal symptoms, so I am never sure what advice applies to me and what doesn't. My major symptoms are: crackly and full ears, postnasal drip, and headache. Sometimes I think it is a sinus headache, but I'm not sure. Claritin seems to help some, but not always. Anyone else experienced this? Any idea what I might be allergic to?
