Hi D W, I don't have any advice, but possible consolation. I had an appendectomy back in October of last year and my incisions, mainly the left one, is still sore. My doctor said (when I went for my follow up) that the sensitivity I was feeling was normal, especially since I didn't take any pain meds, and that my healing process would be slower because I was doing it on my own (without the meds). I believed him at first, but it still hurts, and like you, I have trouble washing the dishes or when there is any pressure placed on the area. My surgery was also (initially) done through my belly button, but because of my weight (I believe)I had two incisions, a small one on the right and a large one on the left. I was also told the pain was because the left sided incision was larger and would take longer to heal. While I do realize the procedure I had is not a tubal ligation, and the pain I experience is not in my belly button (although because of various surgery's, my belly button looks pretty jacked up and is hard from the scar tissue in places), I just wanted to offer some sympathy, and let you know that I experience a similar sort of pain.
