@sears Oh! Well its the medication they inject into your gums before drilling or extracting a tooth. Quite often it is Lidocaine and epinephrine.... am just searching it all as this combination was used months ago when I had stitch put in hand at emerge and after couple of hours sleep woke up to body shaking...... now am going to have to find out if five recent dental fillings and an extraction,... what they used to freeze mouth as started to have internal shaking... ugh, hours spent on on this so far and not feeling well ad am a little bit scared of what I will find!
