Brief Answer:
Proper review, diet, urologist's opinion.
Detailed Answer:
Hi and thanks for the query,
It is important to note that
nerve supply to the bowels, the lower urinary and reproductive areas have the same origins. This is generally from the spinal and lumbar nerves. It is possible that during a bowel movement, there is some mechanical irritation of the nerves supplying the bowels, the sensory impulses are sent to the
spinal cord and further to the brain. Since the nerves carrying impulses to the brain from these areas are same, difficulty in interpreting with clear distinction the origin of the pain might occur. It is what is referred to as "referred pain". This is not surprising and is seen in other circumstances like
shoulder pain could indicate a lesion in the heart, etc. The same explanation could follow after sexual activity.
It is imperative to exclude formally a
urinary tract infection or a
genital infection. A formal urine culture and antibiotic sensitivity test could be most useful.
It is however important to note if you are experiencing any severe constipation? If yes, using mucilage, vegetable rich and fruit rich diets could be most useful. Exercise would be of great help too.
At the level of the testicle, its imperative to know if there is any swelling, any discharge, any history of urogenital infection, history of testicular surgery or cancer. If not, it is possible that this should simply be a referred pain as explained above.
It is difficult for a
prostate problem to be thought of at this age, and also since you do not present with any signs/symptoms suggestive of a prostate lesion.
A suggest you get a proper clinical review again. Get tested to screen for any infections. The opinion of a urologist would be most appropriate in this case, in my humble opinion. Booking an appointment with one would be my advice. Thanks and kind regards. Please, do feel free asking further questions in case you have specific concerns. I would be glad making my humble contributions. Wishing you the best of health.
