Hypersensitivity to amide local anesthetics? Report of a case

The majority of adverse reactions to local anesthetics are either the direct result of pharmacologic properties of the local anesthetics and/or vasoconstrictors or the result of excessive anxiety. However, because of the insidious nature of the symptoms, many adverse reactions are mistakenly identified as allergic. The following case illustrates how knowledge of the above and persistence in evaluation can lead to proper classification of adverse reactions to amino-amide local anesthetics.
