Welcome to HCM and thanks for your query.
The following problems need to be looked for and ruled out.
1. Acute or chronic prostatitis
3. Cancer prostate.
Tests are needed on these lines.
If prostate biopsy
shows no evidence of cancer, a course of antibiotics is needed and PSA to be rechecked.
Tuberculosis tests include urine for AFB, and IVP.
Wishing you good health.
