I had a cold sore on my face/lip a couple days back, that overnight added lip swelling on area around the cold sore. Corner of lip is swollen to 2x it's normal size. Went to regular doctor and he diagnosed as herpes, and asked if I've been kissing anyone new lately. I'm having a tough time with this diagnosis, since no I haven't been kissing anyone. Wife and I are happily married for 18 years, both christian, and not looking. In past, I have experienced canker sores (inside mouth) occasionally, and a dental assistant from way back called it a 'herpes sore' which kind of shocked me at the time. Do you experts agree that this lip swelling in addition to the cold sore are likely Herpes or could they have misdiagnosed this? I also have been a little run down, with allergies, and also experienced swollen neck glands recently. I've been reading lots online and the swelling like I'm seeing doesn't show up in facial pictures. Having a tough time with believing this is what I actually have. My wife gets regular cold sores from time to time, but we never labeled it Herpes. Is it possible we both have this virus, and just now it exploded into this swollen lip symptom? Other ideas?
