You are right that every random pain will stress you out - it may well be stress thats hurting your jaw. Your bone scan was clear. Do talk to them about it though. I imagine there will be some implications around dental care and it may well be something like a regular tooth abscess or vanilla ear infection. Do you have a breast care nurse or other person identified yet? If not, speak to your GP.
Regarding your insurance- do you have any family or other support people you can ask to follow it up? While Public is a good option it might be that down the line some specific treatments could be more convenient going private.
