Well We finally got an answer as to why my dad has been feeling so sick and weak. He has severe anemia and was finally given a blood transfusion yesterday. Now that I've been researching metastatic pca and anemia it is a pretty common occurrence. We have been to so many doctors and told each one of my dads symptoms for he past 2 months and not one of them mentioned anemia as a possible cause. Finally last week his urologist noticed after looking at his CBC that he had anemia. He sent us to the oncologist who said my dads platelets went from 149,000 to 42,000 since November. He sent him to the hospital immediately. We ar so thankful that we found out the cause and hopefully he'll start feeling better soon! Has anyone else heard of this before? My research said that it's common in men on HT. Thanks!
