Thanks for your question on Healthcare Magic. I can understand your concern. Since you are having recent surgery of prostate, we should definitely rule out local site infection as a cause for your itching and hard veins. So get done urinary microscopic examination, ultrasound examination of prostate, clinical examination of penile skin etc. You may need antibiotic tablet, antibiotic cream etc. Avoid moisture and perspiration in private parts. Keep proper hygiene of private parts. Don t worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
