I have had some problems with "caine" type medications the last few months so I refered myself over to an allergist. Seems like when i take any type of these or get carbocaine without epinephirine at the dentist I feel like i'm getting a rush of speed and my body just feels like crap. What does the allergest do and will they inject me with the medication ? ? Cause I dont want to go through that "rush" feeling at all......thnks
