Thank you all! My husband now has tadalafil. I sent his Uro the research provided by Tall_Allen and others (also gave RO the same). He prescribed 5mg tadalafil. Seems nothing is easy anymore. Safeway was back-ordered on 5mg until late July, however, they had 10mg. Back to Uro for prescription for 10mg which we are now splitting. He also takes daily ibuprofen and continues to exercise.
Hubby has finished 8 of 20 RT sessions. Now, for a couple of hours after sessions, he has urgency and pees every 10 minutes. And today, he had the first uncontrollable BM, again within two hours after treatment. All this then seems to clear up. Today he learned he has to stick very tight to the bathroom for a couple of hours. After reading posts, it seems these urgency issues are probably quite normal. Hoping for the best on the rest of treatments.
What a great group you are!
