Hi Welcome to healhcaremagic After going through your query I concluded that you got injury on forehead yesterday and also pain in the jaw can be related to it. It may be possible that you were having undisplaced fracture which got displaced gradually leading to pain. You need to x ray it for detail examination. Analgesic such as ibuprofen can be taken for pain relief. Vitamin B and C is helpful in recovery. You can discuss your doctor about it. Hope your query get answered. If you have any clarification then please don t hesitate to write to us. I will be happy to answer your queries.
