Catch - a little more insight.
My son has a pilonidal cyst and has had it for almost 2 years. Didn't want to get it removed during football, then it would interfere with baseball, then summer baseball, etc. No good time for removal. His doc said that he too would not be stitched - has to heal that way - if it doesn't heal properly, then they have to "pack it" - NASTY. For the uninformed, at least in my son's case, involves about a 4" incision and removal of the path from the cyst to the area where it drains - path meaning all of the skin and 'meat' along the way. Doc said that doing nothing is an option [his partner had one for 10 years - just deals with it b/c he can't afford the down time involved]. Son merely keeps an eye on his [I do, actually], soaks it when necessary and gets it drained when really necessary. Ran into trouble last time by trying to soak it then squeeze it to force it to drain - this merely encouraged minor internal bleeding, which dried and further clogged up the works. We know his is doing well when his skivvies have blood on them - means it's draining and not blocked up.
First time it was drained, doc actually sewed in a 5 inch long tube for a drain, but first, lanced it and dug around a little - a 4 inch long hair popped out - DISGUSTING!! Had the pleasure of going right from the doc's to a JV football game - 3 plays in, gets dumped on the butt by a guy listed at 275# !!! Drained REAL good that night!!
Had 2 kind of funny incidences with his:
1) messing around in gym class: teacher/freshmen football coach smacked him on the can with his clipboard as he walked by [don't give me the "abuse/corporal punishment argument here, either"]. 30 seconds later classmate sees blood running down Tom's legs, teacher almost dies - Tom is laughing, thanked Coach for draining his cyst, it had been bothering him lately!! Coach calls me at home all apologetic - I gave him the same story as Tom - THANKS!! he wanted to report it to the administration - I begged him not to [he didn't]. I told him I figured that for whatever reason he did it, Tom probably deserved it anyway!!
2) Tom out sledding with friends, slips and falls on his tail on the ice, little later leaves in friend's car, after departing friend notices basketball size blood stain on seat!! Maybe not as funny as gym class, but just as effective at draining the cyst!
The good news
: Many times they return!!! [son's teammate last summer had a return/encore presentation after prior removal = kid is 23 YO]. Right now, doing nothing is Tom's best option.
Hope your's works out for you
