Hello, You had a strong orgasm with your wife and since then you are having testicular pain and constipation. Testicular pain may be due to UTI, testicular injury(prolonged erection), urethritis, prostatitis, epididymitis, inguinal hernia, diabetic neuropathy, pudendal nerve entrapment, orchitis, sexually transmitted diseases. Avoid doing any type of sexual activity for a couple of days. Keep yourself adequately hydrated, you can take laxatives at bed time to get relieve from constipation. Take high fiber food and Naproxen or Combiflam, one SOS when needed. Get clinically examined by a Urologist, get required tests & investigations done, so that the pathology is detected and treatment is started at the earliest. Get STD screening tests done to stay on the safer side. If positive you will be treated with antibiotics and antivirals. Treatment for nerve compression or damage involves simple physical therapy exercises that can stretch and strengthen the muscles in the area and relieve discomfort. More severe cases may require injections or surgery. General penis pain is often relieved by the regular use of a top-drawer penis health creme (health professionals recommend Man1 Man Oil). Application of the creme mentioned above keeps the penis skin moist and supple. Properly moisturized, the penis skin stretches more painlessly when becoming erect. Applying vitamin D creme may be helpful. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
