It took five pokes and lots of moving around in each poke to find the fill spot. After the 1st 2 pokes he found the spot and put in 2cc, but wanted to put in 1cc more and after 3 more poke and lots of moving the needle around in each hole he was unsuccesful....... He said the next fill he will do under xray. I now have 3cc as he had put 1cc in during the surgery.:tt2:
