The most common symptoms after surgery include the following: 1. pain, pain is the most common symptom after surgery, usually the most obvious on the day and 2 days after surgery, and the pain may be aggravated by erection at night. 2. difficulty in urination, the operation itself will not affect urination, but may be caused by fear of urination or tight gauze dressing and cause difficulty in urination. 3. bleeding, there may be a small amount of blood oozing from the cut edge after surgery. This is generally normal and does not require special treatment. If the bleeding is excessive and cannot be stopped by pressure, hemostasis is required. 4. edema, which is also very common, usually takes about 2-4 weeks to recover. 5. subcutaneous bruising, which is usually slight and can be recovered by self-absorption.
