it's not bad at all my docter rubbed some alcohol on my belly, then with a bulls eye which was put on my belly by a xray tech he pushed the needle in, then went behind the barrier checked if it was in, it wasn't fully so he pushed deeper. checked a second time and pushed deeper again then a third time it was in and then injencted the solution in and it was finished. it was a little sureal to have a needle sticking out of my tummy for 5 minutes but totally painless tiny pin prick when it went in and then pressure as the docter pushes the needle into the port. I sat up then sipped some water and the docter asked if there was any girgling which there wasn't and I was free to go.
