I Have Seen 2 NPs One Diagnosed Coxsackie Virus But

I have seen 2 NPs one diagnosed Coxsackie virus but after the blisters (2) with white centers didn't go away in 2 weeks my GP NP wasn't sure I had that but did think I had a sinus infection where I have begun Augmentin for the past 2.5 days. I believe my sinus symptoms are getting a little better but I still have t he 2 mouth sores but they now look like little blisters. Does any of this make sens?
