Anyone know what this is ?

I recently got this tattoo last Wednesday and I went on vacation to New Jersey and stayed in a hotel. I didn't notice this rash until I got home from New Jersey that night. I do wrap the tattoo at night to sleep with some kind of tattoo cream.. Could I be allergic to the cream of can these be sweat pimples? I'm lost I didn't have anything like this with my other tattoo. Thanks for the help!
