I received a question about a very unusual piercing placement:
Can you get a piercing on the heel of your foot????????
I wouldn't recommend it. And even if you managed to do it, it would be VERY unlikely to be successful. The tissue there is dense and tight with little or no pinchable flesh. Piercings in such areas is very seldom remain for long--the body simply ejects the jewelry.
Importantly, a piercing in such an area would also have a significantly higher risk of infection than traditionally placed body piercings because of its proximity to the floor where dirt and germs are more abundant
I have seen a very rare placement of a piercing actually behind the achilles tendon the ankle (see Photo, courtesy of Jim Ward and PFIQ Magazine.) Suffice it to say, such a piercing has grave risks including potential for loss of function of the limb.
If you want to get pierced, please select a safer area of your body.
