Hello all Im 19 and had ITP from 8months old until i was 10. Now im 19 and its BACK :S My platelet count dropped rapidly down to 3 (yes only 3 ) and i was quickly put into hospital luckily for only a week. However my arms are covered in horrible purple massive bruises and i have 2 hematomas. Basically my question is how long do these bruises last for ? BTW after steroids and hemoglobin im at 140 now ^_^
