Happy New Year to you to. I don’t know if I can help - your Doc. is probably best for this. I’m ‘sitting’ with a catheter (which I’ve had for the last 3/4 months). I should get it ‘removed’ this month but I don’t know what for? It has been good and bad - it’s starting to ‘get better now’ but that is just at the end - I don’t know what’s next?
First off, your doctor’s wrong about having cranberry juice rather than tablets - trials suggest tablets are more effective (as well as being cheaper and not loaded with sugar). As for using catheters, I can relate to how you feel. When it was first suggested to me there was no way I wanted to do it - the idea of sticking one of them up your manhood obviously wasn’t appealing! But eventually I had to, and it was absolutely fine. It’s not in any way painful - I remember being surprised that I didn’t feel a thing. And I wished I’d started it sooner, as it was great knowing I’d not need to go to the loo for another few hours.
