Are my symptoms eczema?

Hi all! I’ve been going through this weird phase with my skin lately. I recently got a UTI and just finished my 10 days of antibiotics (cefdiner) twice a day. Ever since I started them I began getting supper itchy on my fingers, feet, ankles, and arms. I got bumps wherever I got itchy. My feet are the worst though. Starting today though, I would itch my arms and get these crazy red spots. They aren’t elevated so they’re not bumpy like eczema but the ones on my feet are bumps like eczema.
