When I went for my fill it was a bad experiance. My doctor poked me 15 times kept moving the needle around inside me. He said it's better to find it this way cause it cost less money.Then finnaly he said he felt bad for poking me so many times. He was going to stop. So, then they scheulde me for an ultra sound to see if they could see the port. Of course it dont work with an ultrasound pic. They were just expermenting to try to save money. So, then they got me in to take an X-ray. They found it. But it's really deep so they had to use a longer needle. They said it would have to be x-rayed every time. Until I lose weight. So, now I'am nervous about going back for another one.
