Question: post viral rash?


 nikki5 - Sat Mar 31, 2007 1:49 pm

Hi there..

I am wondering if someone can tell me how long a post viral rash should last?[

3 weeks ago my 4 year old son had a vomiting bug, lasted about 3 days then he was back to his old happy self.. about a day after he started vomiting i noticed small spots on his chest area, and by the time he had stoped vomiting he had a vew more, well becasue i wanted to make sure he wasnt contagious i took him to the dr who said because he'd stoped vomiting that it was just a post viral rash and meant he was geting rid of the virus..

he seems fine but he still has spots all over his tummy, under his arms, a few in the groin area, some on his back, and the occasional one on his leg.. if i run my finger over them they are slightly raised.. they are not itchy and don't look like chicken pox or measels.. he has had the mmr injections...

I am thinking abotu going back to the dr but as i no nothing about post viral rashes, wonder if it can take a while for it to dissapear?

thanks for any help you can give :)[/img]

User avatar Typically, viral related rashes will resolve within about a week, although rarely they may last a bit longer.

Your description is consistent with a viral rash, as is the timing of it. If it is not improving in the next few days I would recommend he be reevaluated.

Best wishes.
