I need advice on a seeping belly button. Started at a month or so and still happening. 4 months post TT. (photo)

I had a full TT with augmentation in January. Thefirst month it has began to seep. It is crusty and has a faint, unpleasant odor. I asked my surgeon and he said it was probably a stitch that had worked out. I keep antibiotic ointment on it but over the last couple weeks m exhausted & last week had a day that I was horribly nauseous and had to sleep for several hours. Now I am consistantly mildy nauseous. It's gotten so that I can only eat a little bit at a time. Can this be connected?
