From what I find on-line there's many different reasons this could be occuring and all need to be looked at by a doctor. Type in bruising in your search engine and wrongdiagnosis****** should come up and look at the different related issues that are assoctiated w/ random un-explained brusing to see which may fit your moms situation best.
my legs are always covered in bruises! Its usually because I always walk into my bed or chairs and tables and stuff. maybe shes just getting them by accisdents like me?
