Ozz, I work in the biggest cancer center in NYC and it is arguably the best in the world. I do my research in the urology department and let me tell you, if BPH or any other urinary issues start to arise (dysuria, hematuria, frequency, ect.) see a urologist. There are a lot of factors that come into play (as you've no doubt seen by doing a search on the matter) but my advice is to really check out some postings.
Another option you could take advantage of, is to immediately get a PSA done from a blood draw (Prostate Specific Antigen). Generally, if it is above a 4, then there may be some cause for concern. Anything below is normal. This is simple, quick, and possibly the most "comfortable" way to see. A DRE is no field day.
Sorry to sound so alarming and your issues are probably just a mild side effect, but my experience (day in and day out) is dealing with people who wait too long to see if there is a problem and ultimately develop cancer. Be smart, do a search, and I hope it all works out, bro.
