Good luck with your medical issue. Fairly common thing that usually does not limit riding DFs, once cleared up. Not usually caused by riding DFs either. I do have a 75 yo buddy who is having to switch to a bent, but his prostate issues are more complicated than normal, and his doc, a cyclist, has demanded he quit DFs. Once he gets past the 'image' thing, he'll wonder why he waited so long.

I have recently switched, to a lwb Tour Easy for long distance cruising. Very sweet machine. My reasons were all comfort related.
