I was turning on my pool filter and somehow electrocuted myself. I'm just wondering could this have done anything to my implant?

Electrocution has no effect on the implants because implants do not have any metal components and should therefore not be affected by electricity. What you have felt was normal. 

Hello,

This should not affect your implants. There is no metal in the implants. The muscle can contract when something like this happens to the body, that is why you felt a tightening sensation. You said your plastic surgeon examined you and everything is okay. Best wishes.
