Tiny bumps that dont itch

[17cna]

A few weeks ago I noticed a small patch of hive looking bumbs on my arm, they didnt itch at all and they were in a perfect circle. I figured they would go away, but they still havent and they are begining to spread up my arm, my left wrist is half covered with small pinkish colored bumps. Most of them are still in circular groupings but a few have randomly spread out over my arm. They do not itch, my mom who is an RN has no clue what it could be. It looks like a hive break out on my arm, but I've been washing my arm regularly and they just wont go away. I work in a nursing home as well, so I am also around lots of people who could have given me something. I was just wondering if you could help me find out what this is, if it is contagious, and how to make it go away. Thank you so much Bethany

Hi, welcome to the forum, infection seems to be unlikely in your case. Your symptoms are suggestive of allergic contact dermatitis, secondary to exposure to allergen and mediated by IgE antibodies. Your skin is known to hypersensitive to certain things when it comes in contact with the allergen.  

Foods and additives like Milk, egg, peanuts, nuts, soy, and wheat are the most common agents to cause such dermatitis. Also allergens which should not be neglected are fragrances (perfume, cosmetics), preservatives (topical medications, cosmetics), rubber etc. This triggering factor should be identified and should be avoided. And even a skin allergy test can be useful.

You can try anti histaminics against prescription, but prevention is the best cure.
Other causes needed to be ruled out are drug reaction. If drug allergy is suspected you need to discontinue the drug and report to your doctor immediately.

I suggest you to consult skin specialist and also to rule out other causes like Tinea versicolor, seborrhea, pityriasis rosea etc. Take care and regards.

dry skin maybe? Try putting some lotion on it to see if it gets any better
