Hello fellow hypochondriacs,
I am in the process of writing the next post - on lung cancer. But to keep you occupied in the meantime I thought I'd post a link to WebMD's Symptom Checker. It's a handy tool - you can enter your symptoms and where they are, and it tells you what diseases you might have. I knew you all would enjoy it as much as I did. I just learned about a new (to me) disease called Floppy Eyelid Syndrome. Luckily it seems I don't have that.
