Allergies?

yes very possible, it could be anything pollen, pet dander, dust mites, etc. your immune system changes almost constantly and sometimes you can become allergic to something you previously werent allergic to, it sounds from your symptoms that it most likely is environmental, (hay fever) but it could be a food allergy as well, try and see if u can take an allergy med for your symptoms or see the doctor if you are worried, it happened to me, tomatoes were never a problem and now i get hives when i eat them!

yes, you're body is always changing. I get new allergies every few years and some actually go away. I'd say you should get another allergy test.

yupp,

you could have developed an allery to pollen, ragweed, grass etc.

with the weather and all, and with your described symptons it's sounds liek your allergic to something like that.

but i take reactine and it's great!

claritine will also do the trick

its unfortunate that we can develop new allergies.. when i was a child, i had 3 cats.. and now i can't even be in the same room as them! its horrible :(

could be dust in your house
