Hi!
It can be overwhelming, and exhausting to keep trying different doctors. I’m UK, so not very familiar with the US system, but a 3d CT is the best scan for diagnosis, most other members have been able to get that at least… Mine was spotted and diagnosed on a panoramic X-ray/ panorex, so it can be seen other ways, but looking ahead most docs prefer the CT, so you don’t want to keep exposing yourself to too much radiation…
If you are thinking of looking further afield, probably again you’d find that you’d need to send a copy of a CT scan to the doctor anyway. There was a recent discussion about what Dr Samji’s office prefers- it’s clarified at the end of the discussion:
Hopefully some US members will give you advice about getting round the system!
