I am about the try out the new P3 Harmony system which is supposed to be a bit lighter, does anyone have experience with this please? I originally tried the pin lock system but it caused discomfort in the distal area of the stump during swing phase especially. I am wondering if the vacuum assisted socket has a bit of this effect also. I love to walk but the changing pressures with each step make me very aware of having a prosthetic and the discomfort it causes. I wonder, does this change with time? I am a one year accident victim.
