Hello doctor,

Post plateletpheresis, my hand is turning bluish black day by day. It is spreading wider and a slight pain occurs in such areas. I have attached pictures of the same. Is this a safe sign? Please help me.



Welcome to

Based on your query and image (attachment removed to protect patient identity), my opinion is as follows:

  • It appears to be previous subcutaneous bleeding.
  • After donation, the vein and surrounding skin will require time to heal.
  • The needle inserted for the procedure is a large gauge needle and surrounding tissue damage will be more. 
  • Pain is due to needle insertion induced tissue damage.
  • Immediate activity will cause internal bleeding, initially mild red, which over time changes to bluish black and would take at least 2 weeks to return to normal color.
  • The pain will reduce within 2-3 days.
  • As it is only at the site of insertion, you need not worry.
  • Rest is necessary for the arms. Avoid lifting anything heavy for another 2-3 days.
  • If you find similar spots anywhere else in body, then it needs attention.
  • Do not apply anything on the discolored area.

Hello doctor, thanks a lot.

Besides the discoloration, I am having a little difficulty in stretching the hand or folding completely near the spot where needle was inserted. Will this also be healed or is there anything to worry about that?



Welcome to

  • Yes, you will be able to fold normally again. Tissue is damaged around the needle insertion and hence rest is necessary for your arms. 
  • Take rest and avoid lifting anything heavy with your hands.

Take care.
