Hi, I have been told in the past I have a low blood platelet count. I was sent to a hematologist years ago and they found nothing. I do get purple and blue bruising and now I have noticed near my ankles and one spot of my arm with small red dots. I recently had knee surgery and they ordered blood work prior to the surgery but said nothing. Should I be concerned and get a third opinion? I was told during my pregnancy I had herpes but it was from a long time ago the dr said. I am very concerned can this be treatable?
