I’ve slowly been increasing the extender sessions. I’m still using low tension - two or three pounds. Four or five hours is the limit of my bladder capacity, so it has to come off for that. I’ll usually do a pump session instead of putting the extender back on.
As time and tension have gone up, I’ve seen some edema. Not up in the cap where the vacuum is; down below on the shaft, around the circumcision car. The usual place for the "doughtnut" when pumping. I have no idea why, particularly considering the area is under compression from the sleeve.
Yesterday was a long session at higher than usual tension, and I got a couple of blisters. Tiny ones, maybe 3mm, that look more like vacuum port blisters than ordinary blisters, though they were nowhere near the vacuum port. I used thumb pressure and massage for a while, which didn’t seem to affect them. Six hours later it looks pretty much the same. Oh, well. When it goes away I’ll resume.

I’m still hitting the gym three days a week, using the recumbent bicycle, treadmill, and rowing machine. The treadmill has uncovered a minor downside to PE. I’ve gone from "severe turtler" to having a three or four inch flaccid most of the time; enough to flap around when walking about. No problem under normal circumstances, but after a mile on the treadmill I have some minor chafing. At a mile and a half, not-so-minor chafing. I get it with either boxers or briefs. For today’s session I had planned to wear the vacuum cap and sleeve, which Mrs. Andy refers to as my "dick armor." Hard to chafe through that. The blister is so small I’m tempted to use it anyway.
