About 5 months ago I had my first and only ever serious outbreak of cold sores on my mouth. Around the time they were developing, I had decided to pick at the pores on my nose and accidentally broke the skin (which I had never done and was quite surprised). This must have spread the virus, because within days I had a cluster of sores on my nose where the skin was broken. After they healed, I was left with this scar. Any idea what is the best treatment? Also for the enlarged pores?
