Steri strips have a little more blood on them 10 days post op

What you are describing sounds completely normal.  However, to be sure I would contact your surgeon and ask for his advice.  He may ask you for photos or ask  you to come in to the office.  The first few weeks after surgery are critical to ensure long lasting results.  A little blood is usually not a big deal but you will want to let your doctor know.  

Thank you for your question and congratulations on your surgery.  It is not uncommon to have a small amount of bloody drainage on steristrips after a procedure and this may spread in the first few days of recovery.  That said it would be best to alert your surgeon to this change in your recovery to ensure there are no other issues taking place and to have the best treatment advice recommended to you - maintaining the strips or removing them.  Hope this helps.
