I have 3, and the one that was uncomfortable was the one were my port was. Unfortunetly my port flipped twice so they had to go back in and open twice, but was right on top of the previous scar so now it is the only one you can see. its been 3 months since the last repositioning and thank God, no pain, no discomfort and am exercising without any problem. 3 seconds and dr. Rehnke was in to fill it no problems. M-
