from your symptoms that you have written you seem to have some bleeding from somewhere,the blood passing from the penis could suggest a urine infection or a urethral stricture
if history of injury to the penile area.
the blood in stools could be due to you developing ulcers due to the history of alcohol abuse
would suggest get a urine test done to rule out infection and kidney problem, you may need to do a micturating cystourethrogram to rule out the stricture.
for the ulcer you need to do barium meal
, and endoscopy
to see if you have an active sites of bleeding. also need to get your liver function tests done with an ultrasound
done to check liver kidney.
would suggest you be seen by a physician to do full workup and give the necessary treatment.
hope to have answered your query.
takecare and stop alcohol it is messing your liver already.
