Infection/necrosis or inflammation? (Photo)

I had a tummy tuck 18 months ago and just had a belly button revision 3 weeks ago. Iv all of the sudden developed redness and swelling with a dark purple line where the incision was. There is also discomfort. I sent my surgeon pictures and he said looks like inflammation. Im currently out of state and panicking because im unable to see him in person. Should i visit an emergency room here or am i safe to wait until i go home?
