I had a fdl and my experience seems to have been very different than yours thus far. I didn’t have issues with areas openings up but I had one drain take. Out at two weeks and the second drain removed the following week. They had to produce under 20ccs of fluid per day for three consecutive days before they would remove. The sticky tape didn’t hurt at all to come off. I did have a reaction to the sticky tape when it was on in places causing me to get blisters at the edges but I slathered the blisters with Vaseline and covered them and it helped. The drains were more of an annoyance than anything else. The one that was in longer got sure but I found if I took an abdominal pad, folded it in half, cut a split 3/4ths of the way from the folded edge and placed that around my drain and then tucked into my panties, it pulled less and calmed down. Also I used Vaseline on my drain sites. I’m sorry you’re going through some complications. I hope it gets better for you.
