As Lucky has pointed out to me earlier:
Since personal medical advice is strictly off-topic here, such questions:
- Should not be answered
- Should be closed
Please, don't answer such questions. Not only are you encouraging more of them by answering, but you can cause harm to the OP.
Personally, if I see an answer to an off-topic question I would leave a comment explaining why the question shouldn't be answered. But I can understand the downvotes, especially for someone who is not a new user or if the behaviour is repeated.
We have problems with a multitude of questions that are off-topic. Please do not answer these and suggest further options. If part of your answer contains Go see a doctor, delete the answer altogether, write a nice comment about the close-reason and vote to close.
I have rigorously downvoted a large amount of answers by old users (expecting they know the rules by now) and left explanatory comments to newer users to enforce this rule.
We can't complain about too many off-topic questions but encourage these kind of questions by answering them!
There are some edge cases. A few good answers by DoctorWhom on questions like "What is X and how can I deal with it" started with "You should see a doctor", but then explained what X is and provided a few treatment options. This seems okay to me. However, simply proposing treatment options or stating that this should be taken to a doctor is not really answer-worth but should be a comment.
