The recovery time for patients suffering from cavernous edema is usually at least two weeks, which varies from patient to patient depending on their condition and physique. Cavernous edema is caused by external factors, such as excessive masturbation and rough sex, or by inflammatory infections. It is less common in the clinic. Mild cavernous edema requires a shorter recovery time, and some patients will recover in a few hours, while severe cavernous edema requires a relatively longer recovery time, usually at least two weeks. Each patient is also different and their body recovers faster or slower. When suffering from cavernous edema, you should go to the regular hospital in time, early treatment, so as not to delay the condition.
