I had my surgery 4/3. I think I needed a drain tube. Week 2 I had a burning pain every time I bent over. One morning I woke up with dried and fresh blood coming from the biggest incision. Went to the emergency. Turns out I had a seroma. Which is a fluid filled pouch behind my incision. I was told it would drain on its own. I ended up pressing around the area after showers when my incision was soft. The fluid came out that way. I had pain for at least a week or so. Perhaps if I had a drain tube it would've gone faster. Hope you're feeling better now.
