I was browsing through this article.I know someone with the disease but they are reluctant to discuss it and the effect it has on them..but they do suffer from severe pain.
However I have to say I found this article made it much better to understand and to see why maybe a cure has been so long in coming..
I'm also glad to see that they may have found a use for Viagra in treating the condition.
