I was advised that I did not need dressing changes as the surgeon would take a look during my post surgical appointment (which was today). However, the drain opening started leaking so I went to the hospital on Sunday and they fixed me up. I then came home and sat on the lounge and got my toe tangled in the drain tubes and tugged it a bit...holy cow! I will not repeat what I said. The thing started leaking again but I left it as I knew I was seeing the surgeon today.
With any luck you will still be a bit numb and wont feel the drain being removed. I hope so.
Take care of yourself.
