I was woken up at 4am by a burning pain at my incision or drain area. I found a small bump on my scar . It feels like something is trying to come out. But the pain feels like it's coming from my drain hole scar... It was always the drain side that felt pinched/burn sensation too. Should I worry!? I'm posting a couple pix to show what it looks like. I will be 4weeks tomorrow!! The bump is about the size of my pinky nail, it's not very big. I can feel something hard under the skin.
