How is nocturnal penile tumescence treated

Patient's question:

Nocturnal deep sleep penile erection, relieved when lying down, wake up about three times each night, each time with erection, no urge to urinate but still erect, daytime penis feels swollen but does not erect, also have a feeling of incomplete urination,? What disease is this, how to treat, thank you

Doctor's answer:

Hello, according to your condition, I think it is likely the symptoms of prostatitis. I suggest you go to the hospital for a check-up to examine the prostatic fluid and determine whether the prostate is bacterial or sterile, so as to identify the cause and seek timely treatment. Once the issue with the prostate is resolved, your symptoms will also disappear. In terms of lifestyle management, avoid spicy and irritating foods, do not drink beer, and maintain a regular sexual life without being too frequent. Wishing the patient a speedy recovery and good health!
