Had Blood Drawn And Swelling In Arm. Applied Ice. Should I Be Worried?
Thank you for your query.
The cause of swelling at the puncture site of vein is due to extravasation of blood from the vein which causes bleeding into surrounding tissue.
After removing the needle from vein, that site should be pressed firmly with a cotton swab for some time followed by applying of a plaster or band-aid so that this will prevent the leak of blood from the vein puncture site and prevents the swelling caused by the bleeding.
You can keep ice for pain relief and to decrease the swelling and while sleeping put the hand on the pillow to elevate the limb so that the swelling decreases.
Nothing to worry and the pain and swelling decrease within 24 hours.
Hope I have answered your query, if you have any clarification please let me know.
Thank you.
