@vacationv, as you can see from these related discussions, 3 months is not a long time after a major surgery like a colon resection:

I'm sorry to hear that you have the added complication of a urinary tract infection leading to prostatitis. I'm tagging members like @troyhenn22 @thull @kkw2 @duckduck2020 @sundance6, who may have some insight.

Vacationv, what is being done to manage the prostatitis?
