This is Dr. David
I am sorry that you are having all of these symptoms.
they sound all unrelated.
how often are you having perineal pain? any constipation?
your eyes pulling themselves shut?
brown sperm is hematospermia and is alarming, but is a very common issue which is not serious and does not point to disease.
the blood vessels are very close to where sperm is created. and a small drop of sperm can cause the sperm to be brown.
is your stool soft? are you having diarrhea?
