always have cold sores in my nose and fever blister on my lips 2 years ago had cold sore on my mouth and not another one since. I have spread it to my children. It seems to me i only have to breath near them and they get it. I take meds for it. I use cream on it. Dextrol cream helps for a few hours and then its usually starts again. When I have it, people around me have dry eyes and itching noses. I am going crazy over this and think i may even get fired from my job
Hello, The cold sores are caused by a viral infection.  I recommend using acyclovir cream for local application.  I also recommend using Acyclovir tablets for oral treatment. Furthermore, I suggest using a multivitamin supplement to boost the immune system.  Hope I have answered your query. Let me know if I can assist you further.
