Hi Ellie! Thanks for the recap, especially for the lists of what worked, what didn't, etc. A great reminder.
I think you should have little trouble finding web sites that already do what you're proposing - give medical consultations - and find employment there? You could be available by e-mail throughout the day, no? You could also explore writing a daily or weekly column, though "lucrative" would have to be scratched off the list.
In my recent bout of neck-itis, I realized that what got me there in the first place was a paralysis about whoat to do about it, who to call (i.e., what type of doctor). My health care plan (UHC) had no help for me whatsoever on its web site, and as a result, I didn't get the help I needed in time to circumvent the acute situation I found myself in. Maybe you could contact insurance companies and propose some type of consultation for their insureds (assuming they give a rat's *ss)?
