I'm with Juju. We were bit 7 years ago, BAD! My hubby, who was perfectly fine, ended up being rushed to the ER (while we were out of town) for what he thought were chest pains. Well, come to find out it was kidney stones, thankfully. Of course, his couldn't be the norm, he ended up having a stent put in in hopes he'd pass them.. Well, they didn't and he ended up having surgery twice...once out of town and the other here at home. To make a long story short, when it was all said and done, the bill was over $25K. Thankfully, they took payments and it's now behind us.

Don't risk it, somethings better than nothing.
