Why does the area below the man turn into vascular edema

Patient's question:

I recently don't know why my lower body is very uncomfortable, and I also don't get morning erections anymore. Please ask why a man's lower body becomes vascular edema

Doctor's answer:

Your condition may be an allergic reaction, which is an excessive or pathological response to certain substances, situations, or physical conditions. It is recommended to use loratadine for treatment. If necessary, desensitization therapy can be considered. Your condition may be due to phimosis, which refers to the foreskin covering the urethral meatus but can be retracted to expose the urethral meatus and glans penis, often accompanied by paraphimosis. Phimosis can cause premature ejaculation. Circumcision can be considered, which may reduce the incidence of penile cancer.
