I Am A Senior Citizen. I Went To The Dentist

I am a senior citizen. I went to the dentist and had my last tooth on the upper right side pulled a month ago. Now I am getting acute pain in the upper lip, cheek, temple and right through the top of my head. It is like an electric shock. It comes and goes but the pain is so bad I can't do anything for the few seconds that it travels I don't know when it will happen again...but it does.....
