Are My Symptoms Closer To BPH Then Cancer?

[lkysplit]

I am a 53 year old male who suffers daily from mid and lower back pain along with a very distended stomach and possible colon. I also have experienced in the past, on again off again night sweats. I also suffer from complete full bladder excessive urination. Even after reducing all of my liquid intake hours before I go to bed? I am also experiencing a slight burning and pinching sensation along with a very full feeling (swelling) under my testicle's in the prostate area. It also hurts during and after orgasm, it starts as a pulsating pain that turns into a burning feeling and then into a dull constant ache that can vary on intensity and length of time.  
I have no health insurance and no money for testing but in November of 2010 I had a prostate exam and my PSA levels checked at a reduced fee community clinic. A Nurse Practitioner diagnosed me with a "very large prostate" but with normal PSAs? She did prescribed me 10 day's of 500 mg Flagyl for possible acute bacterial or chronic prostatitis and then 90 days of 4mg of Doxazosinchronic for possible prostatitis "without infection" that could include asymptomatic inflammatory prostatitis but after treatment there is no change in my pain or condition? Any ideas?  
PS. If it is relevant, my blood work in Nov of 2010 showed my AST & ALT levels were elevated so I recived am ultr-sound that showed an that my liver and spleen are inlarged. So in 12/2010 I recived a chest and abdomen CT and it showed a 10mm dense calcification in the right lobe of my liver along with a 4mm parenchymal nodule in my left midlung, if that helps?
Thanks

I will tell you that early stage prostate cancer usually has no symptoms. Did the PA do a
DRE on you? Also what was your PSA?  Any number over 4 warrants some investigation.
A PSA of 10 or more suggested cancer out of prostate. Not trying to scare you, but just want
you to know. The only sure way to know if cancer is a biopsy. I would not have a TURP, that*s
where they bore out prostate, until I had a biopsy. Once your prostate is drilled out, there*s
nothing left to treat. They also will be able to tell how large of prostate you have. They usually do a Ultra sound during the biopsy.
Good Luck.

Thanks so much for your response mickey, My PSA was 7 and yes I did have a DRE but do to soreness with my prostate my PA was unable to do a "normal probe" but what she did feel was smooth, just very large? The probeing pain was the exact same pain, a dull constant ache but much more intense then I noteed in my above post.
Thanks Again.
