I know this is a zombie thread, but saw that two people have asked about the purpura and thought I might be able to help.
My 16 year old son is being investigated for recurrent petechiae (which sometimes develop into smallish purpura). He gets them mostly on his arms, hands, lower legs and feet, but occasionally on his face as well.
Haematology found his clotting (Prothrombrim?) time was slightly prolonged, but borderline, everything else tested normal so, thankfully, there doesn’t seem to be anything scary going on.
He has been referred on to gastroenterology, as he has had gastro issues since weaing, for which they haven’t found a cause. Haematology think the cause of the petechiae could be malabsorption, resulting in deficiencies in vitamins that assist clotting, ie Vitamin K.
Our family also has connective tissue disorder (some have Hypermobile Ehlers Danlos and some Hypermobility Spectrum Disorder) and apparenlty this can cause leaky veins due to over stretchy tissue. Anecdotally, via support forums and groups, etc, petechia seem to be fairly common in people with connective tissue disorders.
It’s worth a quick trip to the GP, as there is also a condition called Idiopathic Thrombocytopenic Purpura (ITP) that they may want to rule out.
It’s worth noting though that some people just have fragile capillaries and will get bruising resembling petechia from relatively mild pressure, eg cuffs on socks, etc. My middle son has HSD and gets great big stripes of petechia type bruising down his arm, from the cuff, every time they take his blood pressure.
Basically, if you are at all concerned, take her to the GP and get it checked out. Typically, my son had no spots when I took him, but we had photographed some and were able to show both the GP and Haematologist the pictures.
