I'm glad your story worked out to your satisfaction, but I will respectfully disagree about the value of self-diagnosis.
Even with my extremely limited experience, I've already had people angry that I doubt they had acute HIV (Virgin, non-drug user, no exposure with cold symptoms), diabetes (non-fasting blood glucose <100 as measured by this lady at home, she kept a log), and strep throat (rapid test negative, upper respiratory symptoms only). Maybe I was a d*** about it and just didn't realize, but I'm pretty sure at least two of them were just crazy.
Even in those rare individuals who can objectively analyze their situation, relatively few of them have enough of a bio. background to understand all the relevant literature. Fewer still have any clinical understanding of normal/abnormal appearances.
If you have a rare but easily-identified condition, with few other things in the d dx, you might be able to learn more about it. I'd be willing to bet that little of what you learn would be especially clinically relevant.
If someone comes to me with a concern about a specific condition, I'd definitely give it consideration if I had time (if for no other reason than to put them at ease and let them know I heard what they said), but I'm going to take it with a big grain of salt.
