Metal implants.

Metal Implant:
2nd event:
	Over the course of the next year or so, 1967 to 1968, my parents, mainly my dad, began complaining about a pain in his heel.  Eventually, he had me look at his right foot heel for some sort of splinter or spur that he thought was stuck in his heel.  
My dad had me probe his heel with needle where he thought the pain was.  I did this over the course of several weeks looking for this thing my dad thought he had in his heel. 
Eventually, I was able to dig out of my dad’s heel this silver looking metal chip or sliver of metal, it was thin and small but very visible.  It was metal or at least had a glint like metal, aluminum. 
A few months later, my dad removed a piece of metal the same size, from my mom’s heel and my sister’s heel.  
I had one in my foot pad that I took out, too.
