After leaving the hospital hematoma started to be visible on her hips and upper leg around 30 square centimeters on the left and 10 square centimeters on the right , her hemoglobin level dropped to 7 , CRP was 22 according to the doctor that was due to her body being sensitive to the blood thinner used during the surgery , how true is that ? could it be a blood thinner overdose
