I was showering my 7 year DS this evening and noticed that he has a few small patches of petechiae on his body. One patch on his back, one on his inner top arm and two at the top of his chest. They are very faint and not very noticeable, but all around the same area (upper body). We have spent the day at a friends house, where he’s been running around having water fights and playing on their nest swing (he was laying down on it) . I’m inclined to think that, the rashes are in response to abrasion from the swing or rough play because at one point four children all clambered onto the swing, however everything I’ve read online says to get petechiae checked out by a GP. Does anyone else have a child that gets this sort of rash, is it worth getting it checked ? He is absolutely fine in himself!
