5 weeks post-op from lap band removal. Incision from port removal began seeping blood and also looking green and today white?

Hello,
Congratulations on your surgery! I’m sorry to hear your pain has worsened. In general, “new pain” (after previous pain has resolved) is concerning. The drainage and pain you describe could be a normal part of the healing process, or they may also be a symptom on an underlying infection. Evaluation by your surgeon will guide diagnosis and treatment.
Best wishes,

probably you had a bleed in the area. when this occurs if its not so big it dosent matter. the color change are describing an hematoma of the incision. it can be avacuate if cuases pain or is growing, bad smell, hight temperature in area or fever. Otherwise dont worry at all your skin will be ok.Get WellPablo

The fact that you are still in pain and swollen even after that incision has opened up and fluid has drained can mean there is still an ongoing infection present.  The safest thing to do would be to go and see your surgeon so he can do a proper evaluation.
