Does The Swollen Hand In The Injection Site After A Blood Donor Is A Sign Of A Dangerous Disease?

Hello Rina, thank you for the question to HealthReplies.com

Swelling accompanied by blueness in the hands after blood donation is caused due to blood seeping into the surrounding tissues from the punctured blood vessels (usually due to incorrect location of piercing or piercing too deep, there are small blood vessels that are accidentally punctured too, less pressure when the needle is pulled out , or lifting heavy objects after blood donation). This condition is the same as when you experience bruising and is called a hematoma.

To reduce the pain, you can compress swollen areas with cold compresses. If pain is very annoying, you can also take painkillers such as paracetamol. If you see any of the following signs, immediately go to the doctor:

the bruising is getting bigger
very painful bruising
there is red, swollen, felt warm around the bruises
there is an uncomfortable sensation in the hand (for example the hands become cold, the whole hand is swollen, continuous tingling, etc.)

So much information from me, hopefully enough answer
