Hey George:
Great questions. Here's how I handled it:
Had surgery in August when it was real HOT. I decided I preferred comfort to vanity. I figured, who was I going to see who I knew; and, what did it matter if I did? I had my surgery out of town, so at discharged I went to a hotel for a one night stay. I left the hospital wearing a pullover shirt, what I call short sweat pants (to the knee) with elastic waist band (critical). I carried the Foley by the handle for all to see (who cares..I was comfortable). I walked the hotel hallway that night dressed this way. Guess what, the next day I went to the airport wearing the same garb! Got on the plane, sat on my pillow, and when we reached cruising altitude went to the stern galley and stood, holding my Foley, b/c it was more comfortable to stand than sit. Once I got home, I continued wearing the same type shorts with the elastic waist. No underwear. The Foley tube just draped down thru the pants leg. I took walks and short excursions holding the Foley. In fact, I never used the leg bag. Thought it would be too cumbersome and it is much smaller in capacity. Sleeping on your stomach is difficult. You can lie on your side.
Foley was gone 10 days post surgery. Returned to pre-surgery attire.
Hope you find solace with this post.
