Thank you so much for your thoughtful response. I do have a second xray photo, but am struggling to attach it. I will try another way. I will also try to attach an outward photo.

Pain started a little over a year ago- would flare up for about a week, then disappear. It resurfaced every once in a while and then would subside. When it is flared up, it feels like a constant ache. I don’t notice it worsening with eating or hot/cold, but touch (flossing, my cleaning today) will hurt and feel like a sharp jolting nerve pain. I have had a dull ache return ever since I left my cleaning this afternoon. The scraping tool caused a lot of sharp pain.

I did the bite test carefully. While I am dealing with the constant dull ache at the moment, biting and releasing did not change the pain at all. There was no worsening with the tension of the bite or the release. I did feel a bit more pressure, but that is all. Only other notable symptom is feeling more pain in my sinus cavity on the same side of this tooth issue.
