body piercing (Medical opinion)

The use of lidocaine with and without epinepherine is being used often by some piercers to decrease pain. It must be noted that this is a true drug and has side effects. Lidocaine is toxic in high doses and can cause seizures as well as cardiac depression. Epinephrine added to the solution decreases bleeding and increases the durig of the affect but can cause heart palpitations and cardiac problems. Therefore these drugs need to be used very cafefully in areas of high vascularity and absorbance. This is primarily in the gentital region and the tongue. EMLA a topical agent can be applied and occluded with saran wrap or other plastic sustance. This if applied 30 minutes to 2 hours ahead of time will render adequate anesthesia for most piercing if necessary. Furthermore it can be applied to allow for pain control in the immediate post-piercing time frame.
Accordingly, it is an object of this invention to provide a low price plug for use in a piercing mill having an excellent durability.
Another object of this invention is to provide a plug for use in a piercing mill formed with an oxide scale of the plug which has better insulating and lubricating properties than those of the prior art plug.
According to this invention, there is provided a plug for use in a piercing and elongating mill characterizing in that a layer of powder consisting essentially of iron oxides, i.e. FeO, Fe.sub.3 O.sub.4, Fe.sub.2 O.sub.3 or mixtures thereof is formed on the surface of the plug by spraying said powder in a molten state. The powder may also contain oxides of chromium, nickel, cobalt, copper, manganese and alloys thereof.

of the accompanying drawing shows one example of the damage of a prior art plug which is used for a Mannesmann piercing mill. Thus, wear 11 and pealing-off 12 are formed at the fore end, while wrinkles 13 or cracks 14 are formed on the body portion. The wrinkles 13 are formed due to the insufficient high temperature strength, while the cracks 14 are formed due to the thermal stress and the insufficient toughness.
The wear 11 and peeling-off 12 are caused by wearing away of the surface scale thereby causing seizure.
so i guess some types of piercing can cause seizures also i read some where that hitting the wrong nerve tongue piercing and other places on the body can cause seizures if i find the link again ill post it
