The most important thing is that you can get the best out of the situation by going to the urology department or the male department of your local regular hospital for examination, through the examination of exfoliated cells as well as the bacterial culture and drug sensitivity test, and then treat the specific situation with medication. If edema occurs after strenuous exercise, it may be related to obstruction of venous return, and generally does not require drug treatment. You can also use hot compresses, such as hot towels twice a day, to help absorb the edema and make the swelling disappear slowly. The swelling will disappear on its own after the surgical incision heals.
