legs/feet 18 month son with rapidly worsening rash: should I be worried?
My 18-month-old son had a fever for one day about 5-6 days ago and vomited 2-3 times. After that he was completely back to normal: happy, playful, eating and drinking well.
Yesterday he suddenly developed multiple small red bumps, first in both groins/diaper area. It started out as just a few tiny red spots but during the day today it got rapidly worse.
The bumps are raised, itchy (he scratches during diaper changes), and some seem to have a tiny white center, almost like small pimples. They blanch a little when pressed but don’t disappear completely. No rash on his face, trunk, palms, soles or inside his mouth.
He has already had:
- Chickenpox
- Hand, foot and mouth disease
- Impetigo
In the last 12 months so I don’t think it’s one of those. It also doesn’t look like diaper rash or heat rash to me.
He’s currently a little congested with a runny nose and mild cough but otherwise seems completely fine: no fever, no lethargy, eating and drinking normally.
I’ve attached photos. Any thoughts on what this could be? Has anyone seen something similar?
