It can be highly variable - my father had it, one of my brothers, and I had it. Yeah, it's the family male ailment in my clan. To be blunt, the longer you ignore it, it seems the worse the procedure and the recovery. My father ignored it a long time, and had major surgery with major lifestyle changes, an ostomy. My older brother ignored it a short time, and developed peritonitus, and it took that 3 weeks you mention. I noticed it fairly early, and was laid up 10 days, and two of those were because some of the hospital departments don't do weekend work, except emergencies. All of us were younger than Geno when we dealt with it. It's really impossible to predict, without knowing details prohibited by HIPA.
