Quick Question About Urinary Frequency w/ Lupron/Casodex

Hubby only two weeks into Lupron/Casodex and so far no symptoms. Of course we realize it's a bit early for the nightsweats, hot flashes, etc., and we've been working hard to get out front on what we expect might come down the pike. He is now attending cardio and strength training at our local wellness center and still walks (fast) 3 miles every morning (an activity he's been doing for years). We're getting ready to add weights to that walk. He also has increased the number of crossword puzzles he does a week and continues his active mental/physical lifestyle.

He is scheduled for radiation in late August/early September and goes in for marker placement on August 20th. We feel confident in his treatment and his doctors. Of course it took three different doctor consults before we found the doc and treatment choice that seemed right to both of us.

Anyway, he has had urinary frequency for some time now due to the PC, getting up maybe every three hours during the night, but has begun to experience even more urgency over the past few days, last night having to get up almost once every hour.

I've looked around a bit and it seems this is not an uncommon side effect of lupron and/or casodex, but I thought I'd check in here to see if anyone thinks this is something we should follow up on?

Thanks, SC. I'm going to shoot an email to his doc.
