Hi, I've Had Frequent Urination Issues For A Few Years

Hi, I've had frequent urination issues for a few years now (28 yr old man). I've had a camera to check my bladder which was all fine, I had a urodynamics test but the catheter couldn't be inserted due to a 'blockage' and was sent back for another camera check. on arrival, this was refused as they had already checked for blockages?! i'm now awaiting another appointment with my urologist but symptoms aren't getting any better. I now have swollen testicals and have had a persistant (spot like) mark on my pelvis. I'm getting really impatient waiting for my next appointment and am still waiting for any sort of diagnosis??
