I just had a vasectomy 1 week ago. I had two incisions and one had been healing nicely. The second is located on the side of my scrotum so the stitch location is up against my thighs. Of course wearing tighter underwear, jockstraps keep things in place but it is still on that side. I find that as my scrotum relaxes and contracts as it always does through the course of the day, it moves a little and the stitch area on that side is sore. It seems to almost swell in the shape of a small round bump about a centimeter in diameter at its max. After a while it will go back down again. I was worried at one point as I have always been very sexually active and have had an erection in the last week as well and worried even that may be aggravating it. I'm very attracted to my wife and find myself getting excited with her by my side as I usually do but nervous to proceed with this soreness. Honestly though I feel more relaxed when I'm turned on and the swelling seems to be nonexistent during erection. what is the cause of this swelling? is it just irritation and should I wait longer to have intercourse?
