Historia scabbed cold sobre came un contact with muy nipple.... he was sucking hard so it left a little cut on it. i'm so scared. what can i do?

Uncommon.: Relax, wash are with soap and water, apply antibiotic ointment, and sterile band aid, change bras daily. Fortunately, the scabbed over stage is the least infectious. Most likely, since 8/10 people have antibodies to HSV I, you may already be infected before this incident. Minimize stress right now. Breast lesions are rare. http://www.nlm.nih.gov/medlineplus/tutorials/coldsores/id449104.pdf

Probably okay: Once cold sores are scabbed over, they are usually not contagious. Of course, it's always possible that some virus may still be there. If so, and it came in contact with broken skin, it can transmit the virus and cause sores to develop there. Acyclovir can prevent the virus from growing. This can be a painful infection, but not dangerous for those with normal immune systems.
