Thanks Nelie. I didn't mean to scare anyone else unnecessarily, and I'm sorry if my post did that to you. My husband's situation is unique to him, and we won't know until next week what is really happening here. Our best wishes are with you as you continue to heal and recover. Thanks to everyone for your words of support. It's been very helpful. The cat scan is done, and we're going to do our best to put this out of our minds over the long weekend.
