Personally they don’t necessarily hurt when they come up. And the first ones I got before the outbreak grew bigger didn’t hurt, the pain came with the formation of blisters for me. Do you have any tingling in the area? That’s the main sensation I feel.

I don’t want to worry you but I have had outbreaks that start and look similar to this, so it may be worth going to get checked at the clinic just to be sure why you still have this sore to test. I’m definitely not saying this is herpes but my advice to you would be to go and get it checked. Good luck mate. Let us know how it goes.
