Is Chronic Prostatitis Curable?

I am a 31 year old unmarried man. I am suffering from "frequent urination" for the past 5 months. I go wash room 10-12 times during day time and once in the night. In between I consulted with general physician, who carried out urine test and found no problem in my urine. In between I became weak and bit lean. I also started facing low back pain. Yesterday, I visited to a urologist, who made urine test and took ultrasound of my bladder and prostate. He told me that my urine sample and bladder function is OK but there is a slight enlargement of prostate, which causes frequent urination. He told this is "chronic prostatitis". He prescribed me with few antibiotic and anti-inflammation tablet for two weeks and asked to visit again after that. Unfortunately, I couldn't discuss with the doctor more about this problem.
Please suggest is this problem curable. If so how long it will take ? Is this happen to a unmarried young man like me. Is this may hamper my married and sexual life. How can I get strength and relief from back pain. Is there any food restriction needed. Please help me in this regard. Please suggest something more as per your expertise.
