With all due respect to your doctor, I don't think he is providing proper medical care. First of all, can you relay your PSA history? If this is a sudden rise, then a course of antibiotics and a repeat PSA might be helpful, as prostatitis could explain your high PSA and your symptoms.
Your PSA number is worrisome.
I think Zufus gave you EXCELLENT advice. There is a "free-PSAT" test. That is another blood test and a good score on that (here GOOD is a high score, above 25%) would indicate BPH or Prostatitis as opposed to PC. Even better is the PCA-3 test. This is very specific for PC, although all of the tests are far from fullproof. The latter test is easy to do. You udergo a vigorous DRE and then just pee into the glass.
I don't mean to get you all worried, but you really should follow up. You should request a referral to a urologist (or just make an appointment to see one, if possible. Remember, most likely this is nothing to worry about. But, it shouldn't be ignored either!
