Treatment for pelvic pain, low sex drive, difficulty maintaining erection?

Question: Hello, Over the last year, I have had pains and aches in my pelvis. They have become worse and some of the symptoms are making my life miserable. I have no energy, no sex drive, low mood, difficulty achieving and maintaining an erection, aches and tension in my glutes, lower back and legs. It has been two months since I have been able to achieve an erection that could be used for sex. I also have not been having morning erections, random erections and the problem is the same whether I am solo or with my partner. About a year ago, I was having similar issues and was put on antibiotics. This helped to some extent, at least bringing back my erection quality and sex drive and alleviated aches to some degree. I had a digital rectal exam performed and slight sweeling was found in my prostate. I was tested for STDs and had an ultrasound done. Neither suggested any problems. I recently had a period of great anxiety and a battled a flu bug. This made the pains worse and surely had an effect in my interest in sex. This has since subsided, but the other symptoms above have still stayed and become more prevalent. I have been tested for vitamin levels, thyroid, and nothing came back as alarming. My therapist no longer feels like anxiety is playing a role either. I am seeing a urologist in a few weeks but the symptoms are become almost too much to manage day to day. Any ideas? Thanks.
