Hi,
As per your clinical history, please follow like this:
1) Do a clinical examination by your Doctor [urologist] and do few investigations like [CBC with differential, 
Ultrasound whole abdomen, PSA, and urine culture] 
2) Discuss with your Doctor about antibiotics as per culture report along with alpha-blocker. 
Do follow lifestyle modifications like this: 
1) Do take a warm bath (sitz bath). 
2) Limit or avoid alcohol, caffeine, and spicy or acidic foods. 
3) Try to avoid prolonged sitting or try sitting on a pillow or inflatable cushion to ease pressure on the 
prostate. 
4) Try to avoid bicycling, or wear padded shorts and adjust your bicycle to relieve pressure on your prostate. 
Hope I have answered your query. Let me know if I can assist you further.
