Puffy under eye, itchy rash under arms, congested. Slow onset. Lasted only noon till next morning. No food allergy. I work at day care center.

Has this resolved?: Sounds like an allergy- maybe a cream or perfume/body spray/detergent or something that you touched with your fingers (then touched your eye/arms, etc.). If you are not taking other medicines and are not allergic, Benadryl (diphenhydramine) can be helpful. You should see a doctor if symptoms persist. Think about anything new you may have been exposed to- whether at the day care or at home. ...Read more

Can you have contact allergies (itchy skin) from one cat and not another?

The common cat allergens are proteins from the dander that are attached to the fur and in the saliva when fur is licked. There are allergenic proteins in the serum (blood) but likely less of an exposure.... ...Read more

I'm going to be in highschool where everyone uses perfume and I perfume allergy. Can I get used to itchy skin and sneezes everyday? It won't be bad.

See doctor: You may try taking antihistamine or even better a prescription nasal spray on a regular basis to make your nose less sensitive. If these products do not help . you should consider seeing an allergist to get desensitized.

Is allergy an inborn condition?I never had an unpleasant skin allergy(very itchy skin rashes) before until I turned 21.

Yes and no: While you may be born with a propensity toward developing allergies genetically, you actually have to be exposed to an allergen before you become allergic to it. It could happen the first time you are exposed or the hundredth. I, like you, did not start having hayfever symptoms until I was in my 20's. Yet every fall when ragweed is out, symptoms start unless I take my meds during that time of year ...Read more
