I have the same problem. I havent had the cough but I have the same thing and it covers the upper are of the back of my legs and almost my entire buttocks.
ok
this is most likely small vessels vasculitis
it is self limited disease , usualy end by postinflamatory hyperpigmentation
it is mostly idiopathic
but somtimes follow upper respiratpry tract infection
during attack , systemic steroid and antihistamin are benificial
Sorry, how to post new thread in this forum ?
Thanks
