Our whole pelvis radiotherapy journey

February 14th, Happy Valentine's Day! It's been 6 months since he was diagnosed with T3, G9 PCa, two weeks since the last of 23fr of whole pelvis radiotherapy, and eleven weeks since HDR brachytherapy. It's three weeks until his third Prostap 3 injection, and his follow up appointment is scheduled for the beginning of August. He's still taking tamsulosin in the morning, but peeing no more than 250ml each time throughout the day. There's been no sign of blood in his stools or on paper for 8 days, though the consistency is still soft, and he needs to go 3 times a day. He says the hot flashes aren't too bad up to now, and the fatigue comes & goes, but is tolerable. He goes to bed around 9pm, wakes 2-3 times to pee, then can't stay asleep after 3.30am. Thankfully this isn't a problem, as he's used to odd sleep patterns, due to recently retiring (12 months ago) from being a tramper class 1 hgv driver. He walks ten thousand steps most days, and says that he feels good, and other than the occasional paranoia of wondering what the slightest pain or twinge is, life has gone back to normal, and we're enjoying the freedom from the monotony of having to go to The Christie 5 times a week. The time leading up to and during treatment has dragged & flown in equal measure, and if it wasn't for this forum, I'd most likely still be as hysterical as I was in the beginning. 

Four weeks now since the last RT, and still feeling ok. Things are much the same as my last update, though there was a little blood in his stools of Friday, but nothing since. The past four days or so, he's said he's had stomach ache/cramps, sometimes before or just after a bowel movement, but they didn't last long. He's also mentioned a dull ache in his pelvis. Does anyone know if this is because of the RT, or the Prostap, or because of the extra walking he's been doing, or just a mixture of everything?
