Hi Jade,
Glad to hear that great news from the dentist. With all due respect, I'm not doubting you are experiencing symptoms that concern you, but several doctors and now a dentist found nothing that concerned them. Could it possibly be that you're suffering from a little bit of health anxiety? In the mean time, while you're waiting for the system to authorize appointments, perhaps a conversation with a counselor concerning your fears would be beneficial.
Positive thoughts and prayers
