Unknown Cause for Rash

I have this rash on my arms, hands, torso, legs and on the top of my feet.  They look like small red spots some of them are flat, sort of like the measles.  The blood work came back normal, so my doctor doesn't know what this my be nor how to treat this.

I had a flu symptoms  a couple of days before the rash began.  Does anyone know what this can be?  I am taking steroids in hopes that this is an allergy, but this itchy rash is worse.  Please help, thank you in advance!!

Hi,

This could be allergic reactions to unknown substances, skin hypersensitivity, eczema, dermatitis or sun rash.

Do you notice the lesions trigerred in response to a specific stimulus like sun exposure, some substance related to your work place?

You should try to keep the area dry and clean. Try some powder to absorb the sweat.

Apply calamine lotion at the site and take some oral antihistamine medications for your complaints.

If the symptoms are still persistent, consult your dermatologist and get a proper clinical evaluation done.

Let us know if you have any doubts and keep us posted on how you are doing.

Good luck.
