Hi,A couple of nights ago around 3 in the morning my niece was not sleepy so she was on bed using her computer when she noticed she was bleeding from her arm. She had too small punctures on the side of her right arm around the elbow area. She said the blood was actually coming straight out and not just like a normal bleeding. Well, last night around 10 pm the exact same thing happened on the same place but just like 1/2 inch away from the other two punctures. now she has 4 little red mark (small like a pin head). We took her to the Dr and he only gave her a shot to prevent a hemorrhage and tomorrow we are taking her with a different doctor for more test. Wondering what's causing this to happen. She is 16 years old, like 5'4, and weights around 140 lbs. Appreciate your advise.
