<s>[INST] Our 5 month old had a fever for 2 days, and then developed a round red spot with a raised center that was filled with puss in the nape of her neck, the size of a silver penny (under her hairline). She also developed two smaller pimple sized spots in the back of her neck but which dried up and went away. We have been treating it with topical antibiotic. Is this something we need to seek medical advice to for? [/INST] Hi... Thank you for consulting in Chat Doctor. Skin conditions are best diagnosed only after seeing directly.
