I too have had septocaine 6 months ago for a root canal on a left upper tooth. Afterwards I started having weird sensations in my temples and tingling in face , high blood pressure, I have never had high blood pressure in my life. Now 6 months later I started having a numb left upper lip then it progressed to my left upper mouth, side of tongue, cheek,up to eye.This has been everyday now for 2 weeks. Also feel dizzy and diosoriented with stomachache. Can anyone tell me if they have had similar effects and will it go away.
