Tape Blister? What do you think may have been the cause of this? (Photo)

Thanks for your question and photo.It appears that you may have a small reaction to perhaps a drape or some minor irritation from the tension and stretch on your skin after surgery.  Make sure to follow up with your plastic surgeon.  From the looks of the photos it should go on to heal without trouble.Best Wishes

The small blister does not appear to be associated with taping. They have a square edge usually. It looks minor, but talk to your surgeon.
