I'm sorry to hear that, and I hope you'll consider natural remedies rather than harsher ones when possible. It sounds like referred pain to me, perhaps, although you need to go to a specialist. I have no images or visuals, and you need to get some x-rays and answers from someone local. Make the appointment today. Symptoms could simply be related to clenching your jaw due to stress, and referring the pain to the zygomatic arch and temporal bone, somewhat common. If you have a sensitive tooth or cavity, this could also refer pain to that area. But with your pre-existing condition, you *need* to act right now and make that appointment. Just get it checked out.
