Be honest with people about your condition and how it causes bruising, often without you knowing the cause.

I don't take any meds for my condition.

I just tell them it’s ok. I’m used to it. Its part of the bleeding disorder. But I have my had bruises like that since my diagnosis. Do you take your meds?

My youngest daughter has problems with bruising due to her Delta Granule SPD. For years I was accused of abusing her because of the bruising. Unfortunately, the only thing that has worked with her school/work/Girl Scouts was to educate everyone important that she would interact with.
