Lately I have been having urine remain the shaft even after minutes of trying to clear the urine out. Today I went to the bathroom and took toilet paper like normal and tried to get the urine out of shaft but I under estimated how much was still inside and something happened some blood started coming out. Within 10 secs I got really dizzy and disorientated and almost did not make it back to my bed (Almost blacking out). Another few secs I started getting extremely clammy and profusely sweating (Pouring off me). A very loud hissing noise was in my ears but my wife said she heard nothing and I started to get numbness in my private section. Within 10 minutes it all started to go away except a burning and tinkling in my front private section and weakness all over. What could this have been?
