They don't appear to be fluid filled. Yes I've had a sore throat. No past significant medical issues.
The Dr I visited yesterday did not think it was a cold sore, but he did not really know what else they might be. I have had cold sores in the past many years ago and this is quite different - they have not burst and scabbed as they normally would. I took zovirax tablets at the onset of my sore lip. I am worried that it is now 12 days and there has been no improvement. Could it be anything else?
I have an appointment for Monday with another Dr. If I use canestan cream until my appointment and it is not thrush could this make my lips worse?
