Decreasing Rbc

It sounds like you might be losing enough blood continuously to make you anemic, so this needs investigating, probably by urology, but maybe by colo-rectal too.

Do you ever pee bubbles or gas?

It seems surprising that you've had so many tests and no-one has offered an investigation or a reason why. 

Unless HIFU has such side effects, 18 months seems a very long time to have bleeding.   It might be nothing to do with the prostate and could be something relatively benign such as an ulcer in the intestines or similar although it could be a lot of things.

If it was me I'd ring the GP on Monday.

All the best, Peter

Peter,

I went to GP about blood in Semen and he said its common and should go away within 6 months.  18 months later ...

I did have a urine test that found blood and was referred to urology.  They took a look inside my bladder but found no source. Nothing further.

Went to GP about blood in stools. He checked for fissures but none and said it should go away by itself.  Still get some bleeding sometimes.

I guess each individual thing is minor. But I am concerned that noone is actually considering the above alongside PCa, CKD and steady decline in bloods.

If I'm totally honest I dont have a lot of confidence in some of the doctors.  I went to one appointment where she googled the symptoms and printed off a web page to give to me!
