Thanks for your query.Based on the facts that you have posted it appears that you have difficulty in passing urine and have been diagnosed to have Prostate
Since you are just 47 years old it is unlikely that you have BPH
The cause of your symptoms could be something else than BPH.You need to get investigated thoroughly to find out the cause of urinary retention
Please consult qualified Urologist
for clinical examination and detail assessment to conclude your problem.
