Should I get a second opinion with another urologist?!

I was diagnosed with prostatitis and epididymitis about a month ago. The doctor did a DRE and noticed I had a hydrocele on my left testicle and diagnosed it as the above. He prescribed me with Cipro, but I had to stop taking it due to side affects and bactrim seemed to bring out my allergies. I then took Doxycycline for 15 days and I felt pretty good, but as I got closer to the end of the meds I started to feel the same. Now I feel like I gotta be all the time and I have hesitancy starting my flow. I also have a weak flow sometimes and a little dribbling/leaking. So today I went back for a checkup and he just prescribed me Flomax and said to see how I feel. The thing is that Flomax will not necessarily get rid of infection if I have one. He didn't even tell me if it was due to infection or anything. Basically I feel like I should see another urologist and see what he says, and I don't want to be on Flowmax for the rest of my life. I am only 23. Should I get another opinion?
