I have been bruising just on my arms for the past 6 months, large and small, all over my arms, i currently have 21 small bruises on my left arm and 4 on my right arm. They vary in size. I am not on a blood thinner. I have had the routine bloodworkup and a PT and INR done. I have been in the health field for over 25 yrs and have never seen this. Nor has my Dr. I am trying to get a consult with a Hematologist. What do you think??
