I experienced a slight and intermittent numbness in my left cheek from several weeks ago. I have also experienced tension headaches.
When a patient experiences numbness in the face I usually want to evaluate that patient IMMEDIATELY. It could be an upper tooth infected, the Temporomandibular Joint Syndrome, Transient Myeloproliferative Disorder, a neurological problem or otherwise. Need a good medical history and examination. Do not hesitate to see your doctor, as it has been several weeks.
