How do you feel about this question: What can cause a lump in the middle of the neck??
The question is clearly not "personal" medical advice, but it can clearly be used as such. I feel that answers to this (and similar questions) could be used as medical advice by future visitors of the site, and I therefore feel that they are potentially dangerous and off-topic. Even if the OP has now included a full medical history to help with the diagnosis, I still think that this should be off-topic for the site, since diagnosing over the internet based on a short medical history is risky.
What do you think? Off-topic or not? Am I being too restrictive?
