Revision septoplasty - infection? hump over bridge?

Had a revision septoplasty with rib cartilage and fascia graft - 6 weeks post op - and now have bump on bridge of my nose that goes red - contacted surgeons office - surgeon is at a conference - she suggested seeing my gp if im concerned about infection, is this a good idea or should i just wait till next week to see him, the redness comes and goes - the hump over the bridge (which wasn't there pre-op) remains. It appeared after 5 weeks. it also feels hard - thoughts?
