A few weeks ago I came across this question. It was pretty interesting to me and I figured it was one that I could handle answering. In the beginning, I had some communication with the asker, simply because I wasn't sure I understood the question. I edited it to make it clearer and then proceeded to answer. So on and so forth...
Anyhow, the person accepted my answer and left a comment, which I responded to to the best of my ability. This pattern continued and has continued up until today (and I'm sure today wasn't the last time I'll hear from the asker).
The person is continuing to ask questions within the comments; which I personally have no problem with... However, it appears to me like they have been asking the same question every way they can think of. So I have provided short, tidbits of information back; answering them as best I can. They also un-accepted my answer. I was a bit miffed. I understand that maybe they did it because I hadn't updated my official answer to match what I wrote in the comments. I did let them know that I do have every intention of editing my answer - as you can see, I haven't yet though, I'm busy and have life going on. So, my problem is, this question got out of my I'm-comfortable-with-handling-this realm long ago and I've been doing Google searches and flying by the seat of my pants trying to answer these questions. The only reason I'm remaining involved in the conversation is that no one else ever got involved and I don't want to to leave the asker dangling.
So! My question is, where do I go from here? I'm thinking about responding to the person asking the question and giving them contact information to someone who could perhaps give them better information, like Johns Hopkins or The Mayo Clinic.
