I am 16 days post TT and my belly button is burning, is this a concern? (Photos)

I had my surgery 16 days ago I cannot stand up straight and my belly button is burning and I have a tugging pain from the inside. The spots on my back where I had lipo are warm to touch and very swollen. I’m not sure if these are all normal symptoms or if I should go to the er, my sutures are also very red, I’ve contacted my surgeon and his assistant said everything was normal. I also have been very nauseous and I have Diarrhea.
