1 /5 Lashonya Shabenas: I wish I could give a negative zero! Let me start by saying, if you dont know an alternative to a medication that a patient is allergic to then you need to quit!! I was in severe pain and it was obvious the tooth needed a root canal and there was infection. Not rocket science. You shouldnt be asking the patient what you should do. Left with a numb mouth ( I had to tell you where to add more (Novocain) and nothing was fixed. I had to call my primary care to see what i could be prescribed in addition to the pharmacy. Get out is their!!
