I have a scar on the left side of my neck. This is where my intrajugular (IJ) catheter was inserted. The said catheter was needed in the early phase of my dialysis. All hemodialysis patients had experience having a catheter inserted in their necks. It was there for two months. When it was removed, a scar was formed. For your imagination, it looks like a hickey. It makes me look like a womanizer letting anyone suck my neck. I wish lol.
