Since the past 3 days, i have swollen feet, ankles, calves, and swollen foreskin. i can also feel a palpable mass in my scrotum. what could be the diagnosis ?

Edema: You may be having multiple problems here. Swelling of feet and legs is a very serious sign of possible systemic diseases. You need to see a general doctor right away for any swelling of the lower legs. Hypertension, heart failure and many other diseases may be a factor!

See a doctor: It is difficult to make a proper diagnosis since I am not there to see the condition. I recommend seeing a doctor so that they can make a proper diagnosis and give you something to get rid of the condition or relieve symptoms.
