If you’ve donated plasma recently and are now dealing with bruises and aching arms, you are not alone. Many plasma donors experience similar issues, and it doesn’t mean the process was performed incorrectly. Bruising from donating plasma is a common side effect and fortunately there are some things you can do to reduce the discomfort, swelling, and bruising.

What Is Plasma?

Plasma is a vital component of blood, and it plays a major role in helping our bodies maintain homeostasis. It is composed of water, proteins, nutrients, and antibodies that help fight off infection and disease. Plasma is used to treat a variety of medical conditions, and it is commonly used in transfusions, wound healing, and treatments for burn victims.

Why Do People Bruise After Donating Plasma?

Bruising after donating plasma is a common side effect and typically occurs due to the needle puncture made during the donation process. The needle is inserted into the donor’s arm and connected to a machine that collects the plasma. The needle and the accompanying pressure can cause the veins to become irritated and inflamed, resulting in bruising.
