So apparently, we've agreed that medical questions are off-topic here, largely because accuracy matters, and we can't take the responsibility to judge serious medical issues through the SE format -- it just won't end up working well. I agree with that.
However, I think that some medical questions should be acceptable here, like "how can I close a cut if I don't have a Bandaid on me?," and "what can I do to make a mosquito bite stop itching?" and similar questions. These problems won't cause too much harm if they're mishandled, and (I think) comfortably fit within Wikipedia's definition of "lifehack."
What does the community think about this? Need we make all medical questions off-topic, in order to protect the site's users?
