Hi,I never had allergies when I was growing up in South Africa.  I am now a au pair in the United States since June 2010.  Last week Thursday when I went shopping at a mall that I usually dont go to I tried out a perfume with my friend which I also do not usually do or wear.  I also tried on some clothes.  On the way home was the first time I remember feeling unwell.  My ears started burning so I took out my earrings.  Then that night my ears, eyes and neck were itching.  I sneezed for a few minutes after the perfume while in the mall but that was the only sneezing and there is no rash on my arms. The next day my eyes were swollen closed and I had a red like rash on my next and sandy grainy bumps behind my ears.  I can keep the swelling down quite a bit with benedril but after 5 hours it comes right back.  And although the swelling is down with the pills my eyes are really red, wrinkly, puffy looking.  This year i have removed 3 ticks after walks in the park.  The only unusual food in the last 7 days was a persimmon but I have eaten those earlier in the year and nothing happened.  I tried changing my soap and lotion yesterday and nothing changed.  Could it be that I ate some Christmas treat at church or Christmas smells in the stores?  Last year I had a cold at Christmas time and my eyes were fine and no rash.  Please help it looks like I have aged from 22 to 40 over night:(

Hello, I read carefully your query and understand your concern. Your symptoms seem to be related to an allergic reaction. There are many possible allergens that cause the allergic symptoms. The exact allergen can be confirmed through allergy tests. I suggest using antihistamines such as Cetirizine 10 mg daily. If the symptoms continue, you may need steroid shots. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.
