Although bruising is common, donors can take action to avoid bruising. If you are planning a blood donation, avoid wearing tight clothes, as this can create unnecessary compression on the veins. A skilled phlebotomist will also be able to offer advice that can help minimize bruising. Throughout the donation process, it is important to follow any instructions your phlebotomist gives you, as this can help ensure a painless donation and decrease your chance of bruising. Fortunately, the science and technology associated with phlebotomy are always improving. Hospitals have even recently begun to introduce a new needle designed to decrease the pain associated with blood draws. Knowing this, you should be able to walk into your blood donation with confidence.
After your donation is complete, you should be careful with the arm that was used for a donation. Although you might not be feeling any pain, your body still has to work to heal itself following blood donation. After you have donated blood, a small clot will begin to form over the puncture in the blood vessel used for donation. This may sound alarming, but it is completely normal. However, agitating or exercising the donation site may dislodge the clot and cause blood to leak out into the arm. For this reason, it is a good idea to avoid choosing a donation site in your dominant arm. If you have the opportunity, you should sit and relax for a few minutes after your donation. The healing process begins immediately after the donation has ended, and it is in your best interest to allow this process to occur unimpeded.
