Hi there Mia. I read your predicament with interest. At the outset, do you have any psoriasis
or any blood disorders in your family? How old/young are you exactly? Is there any associated joint pain..knee & /or ankle associated? Is the rash
itchy or are those bruises spreading? Do you have any other skin issues with scaling skin in the past & /or something mimicking severe dandruff? I do think that this eruption calls for the attentions of a dermatologist
& please do go across & fix an appointment with one. Also, a skin-biopsy
may be required to help clinch the diagnosis. I envisage this will probably be an entity that fits into a group of disorders called papulosquamous disorders or a localised skin infection
...both very simple to manage & nothing to worry about! Perhaps an antibiotic course will sort you out if it is the latter but Yes, time for a Dermatologist's Intervention @ Ground0! Hope this answer has pointed you out in the right direction & Good Luck & wish you a speedy recovery & a clear skin soon!
