Allergic reaction???

I have these bumps on my chest under my boobs and going up my necks.. I'm worried that it might be an allergic reaction to my body wash but I haven't used it in a couple of days now.. At first it was just on my chest (Wednesday) now today being Sunday it is starting to show up on my neck.  I getting kinda worried cause I have a 3 y/o and I don't know if it is something I should be worried that she could catch if it is contagious.  I know it isn't chicken pox cause I had those when I was a small child and I have kept myself under a blanket to stay warm and nothing else popped out like chicken pox do.  I'm not sure what it is but I'm starting to get very concerned about it. Can anyone help me so I don't sit here and constantly cry worrying that my daughter can get whatever this is if it is in fact contagious????

Hello,
From the symptoms it can be contact dermatitis, allergic reaction, heat rash, sweat dermatitis or pityriasis rosea. Avoid using any lotions and creams for the meantime. Use a mild cleanser with moisturizing properties like Cetaphil. Also use cotton clothes and change the clothes twice if there is any increased sweating. Try keeping the skin free of sweat as far as possible. If the symptoms still persist then you can apply mild steroid like dermacort. For the itching antihistaminics like Benadryl or Claritin can be taken.

I hope it helps. Take care and regards.
