HiI have had pain in the left side of my face for a week now. I have been to my dentist who put me on a 5 day course of Amoxicillin 500. I feel quite sick and periodically feel as if I have a temperature. Today  the pain is just in front of the ear in the top jaw. Also my head feels really fuddled.Any ideas?Linda
Hello, thank you for consulting with Chat Doctor. As you are mentioning that you have pain on the left side of the jaw in front of the ear, then there can be two possibilities for it-First is there can be any infected tooth in the upper jaw which is causing this problem. -Second is maybe your joint of jaws (Temporomandibular joint) of left side is creating the problem the problem is of tooth the dentist must treat the tooth as only antibiotic will not solve the problem. And if the problem is arising from your joint then antibiotic have no role in it, as it will be relieved by some muscle relaxant. But for both the conditions you should visit your dentist again and get it confirmed with detailed examination with x-ray of the tooth and joint, Hope it will help you.
