This is the second time that I've experienced a reaction to local anaesthetic that was administered by my dentist. I become drowsy during procedure and afterwards (yesterday) I developed light headedness, severe nausea (still lingering), shakes and tremors. Vision blurred. The nurse gave me dextrose tablet and on gums. I was tipped back on a bed with a fan on me, I wasn't cold. After a while I felt that I could sit up (I desperately wanted to go home, I was feeling very ill and didn't want to end up in hospital, I avoid that at all costs) I was still weak and dizzy. I relapse afterwards and feel very ill. Has anyone else experienced this kind of reaction to local anaesthetic?
