I thought that that surgery was the only answer to this annoying problem so I went on the internet looking for something that might help and found ZIRO. I thought I would give it a try. That was about 6 years ago. It works. It doesn't cure it but it makes it totally manageable. I don't even think about it anymore unless I run out. There are many day's I don't even need it. One tube last me about 6 months so the cost is insignificant per day.
