Full Answer

Bruising after blood donation also happens when the needle is inserted into the arm and damage to the other side of the vein occurs, says the Australian Red Cross Blood Service. This creates a tiny hole through which blood leaks. Bruising also occurs when one of the fragile blood vessels below the skin gets damaged, resulting in bleeding. Bruising usually does not become immediately apparent during the donation period.

Large bruises occasionally develop after donating blood, notes the Australian Red Cross Blood Service. Some bruises appear while at the donation site, while others appear one or two days later. Although they tend to look serious, these bruises are generally harmless and disappear over time. It takes up to two weeks for the bruise to go away completely. While donors cannot always prevent bruising, they can minimize the size of a bruise by applying pressure on the area of the skin where blood was taken until bleeding stops. It is also important to wear the bandage for four hours after donating blood.

    How do you get rid of a black eye?

    A:

    According to WebMd, the best treatment for the bruising that accompanies a black eye is to apply an ice pack for 10 minutes and then remove the ice for 10 minutes to prevent damaging the surrounding skin. The cold compress stops the bleeding under the skin and limits the amount of bruising. For convenience, a bag of frozen vegetables can be used in place of an ice pack.

  • Q:

    What is a bruised vein and how should it be treated?

    A:

    When veins tear, a bruise develops. The Mayo Clinic states that a simple scrape or fall can cause bruising, even if the skin is not torn; the harder the blow, the larger the bruise. Bruised veins heal naturally, though resting and applying ice to the bruised area help speed the healing process. Compression wraps and elevating the bruised area also stimulate healing.
