Are yellow sore spots on the lips canker sores?

Can canker sore and heroes be distinguished by a picture?
I got diagnosed with heroes simplex by a Thai doctor, but after much research and starting to think it’s canker sores.. so the antiviral I’m taking would be pointless?
Only sore in the inside of my lips. No blistering just white/yellowish sore spots, extra painful.
And I took 4grams of Valtrex when my lip was just itchy and they still developed. Also my
First oral sore ever.

HI, thanks for using healthcare magic

If it is a canker sore then the anti viral would not be useful because these are not associated with viral infections.

These may occur if there is injury to the area, allergies, use of spicy foods etc

Use of a spray or gargle like diflam or chloroseptic would help because these have an antiseptic plus pain killer

I hope this helps
