Yesterday i had blood draw from my arm and today, i scratch it and now a knot came up as a size of a dime, is this normal and should i be concerned?

Not unusual: The knot is from bleeding under the skin after needle was removed. It's called a hematoma. It will resolve in a week or two just like a bruise would. No cause for alarm. Thanks for trusting HealthTap!
