I’m sorry to hear of your problem.
Researchers have recently found that some people may be genetically more prone to cold sores because they do not produce enough of an immune system protein known as interferon-l.
It could very well be that you are one of these individuals.
Cold sores are recurrent infections and the best way to prevent them is to work on strengthening your immune system and I hope that my new blog article - 'Cold sores – new news for an old problem' can help.
If you can identify triggers for your cold sores, avoid these like the plague if this is possible.
Treatment of cold sores when they do occur is another matter.
You say that you have tried a number of different creams. People respond differently to these preparations and I am afraid that for someone in your position with recurrent bouts of infection, it is a matter of seeing what works best for you.
If you haven’t already done so, try using propolis. It may be worth giving this a chance as many people suffering cold sores have found that it works well to resolve symptoms when the infection breaks out, as it can be used at every stage of the cold sore.<br="">
