I have been bruising very easily.Mostly my lower arms and legs.  I researched it on line and it does resemble purpura.  Just a rub can result in brusing which takes weeks to go away.  I am not on any blood thinning meds and do not take aspirin.  Can you give me a cause and/or treatment?
By your symptoms and zero Chat Doctor. .it is also a cause of purpura like thing ...but you need proper evaluation ...so please visit a rheumatologist ...
