So today, after a week of feeling near normal, back in regular cycling gear, gel gap seat working great, some good news (I hope it turns out when I see the spine guy): no internal issues seen by camera up belly this morning. All nerve-related from disc issues, no BPH, no sign of the big C, or anything else.
Still have the damned tube, but clearer hope now, too.
