benign prostatic hyperplasia
"I've had a weak stream for some time, but after a recent prostate biopsy, I had extra trouble voiding.  Actually, I was just dribbling and couldn't even get up a good stream.  In the mornings I wasn't sure I would be able to urinate at all.  After one day, I noticed I was getting a little bit better flow, but it immediately causes dry ejaculation.  I took a second day and developed a headache which carried into the third day.  This morning I was so tired and lethargic I lay in bed till noon.  I decided at this point that I would get off it and see if my energy comes back.  I believe I will have to opt for surgery and get this fixed."
