Hi, I'm 19 days post-op. The night before last I noticed the scab on my biggest incision had fallen off and it was leaking yellow fluid. It seemed to seal up overnight but today it started again, and it's more orange than yellow. Is this dangerous??

There's too many factors to answer a question like that over the internet. LOL. The signs of an infection post-op are fever, high pulse, pus from the incision, a mass/swelling at/near the incision site, increasing redness at/around the incision site, severe tenderness at/around the incision site.

If it's just a tiny amount, then it's probably just serous Fluid from the healing process. If it's a significant amount, it could be something starting.

If none of the symptoms I listed are present, then it's probably not cause for a run to the ER. I'd advise calling and seeing if someone is available in your surgeon's office to give you some feedback, and maybe even see you if they think it's necessary.
