Does it hurt??
No. I was worried myself, even asking if I should take pain meds before having them removed. Surgeon said not to worry.
They were out before I even knew he had pulled them out. NOTE: my drains were in the front, in the groin area, 4 total. Two of which fed all the way to the buttock.
PS. I also wondered it they stitched the hole that the tube came out of, no. They just put compression pad on it with some tape and it heals closed on it's own. NOTE: it may ozze a little , but no big deal.
I had 3 with my LBL-one came out of the top of my thigh on the left, the other two same spot on the right. The left was pulled first-within a few days of surgery. It felt like a snake moving under my skin-no biggie. When he pulled the other two a week later, it helped when he "drew" on my body where it was, so I'd know what to expect.
All in all, I worried needlessly. It was far more wonderful to be without them!!
