Symptoms of cavernous body damage include severe pain, loss of erection, hematoma and so on. 1. Severe pain: damage to the corpus cavernosum of the penis will cause severe pain at the site of the damage, and a sound like cracking can be heard when it breaks. 2. Loss of erection: After damage to the corpus cavernosum of the penis, the originally erect penis will become soft and curved, causing the penis to favor the uninjured side. 3. Hematoma: Because the corpus cavernosum of the penis is rich in blood, hematoma will appear after the injury, and the penis will be swollen, with bruises and petechiae appearing on the surface of its skin. If the symptoms of spongy body injury appear, it is recommended to consult the doctor in time and treat it actively under the doctor’s guidance, so as to avoid infections and dysfunctions of the urinary system and so on.
