I've just returned from a consultation with the surgeon I had been referred to for the aching lump on my jaw. He says he is certain there is no tumor. He acknowledges that something is amiss, but is confident it is a dental issue. He detects a swelling of the periosteum of the jaw (membrane surrounding the bone). So, no emergency, no panic. Current treatment plan is two weeks of ibuprofen. moist heat, come back in two weeks. If not better, repeat panoramic x-ray and consider extraction of the wisdom tooth on my lower right jaw. No need for biopsy or MRI!!!
Further good news is that this fire drill caused me to plan for eventualities that are difficult to face and I've arrived at a plan that gives me comfort, peace, and even joy! I think my plan should also do the same for others involved. So, given that I have an extended period of time to work with, I think I'll go get started with some of the lowest items on my bucket list.
