I am sorry to hear about your pain and suffering. I too have been suffering with a recurrent prostate infection which is thankfully getting better as I have been following a protocol of diet change, supplements, and (the last resort) Cipro.
First I began following Dr. Richard Schulze' protocol for prostate problems, with a good saw palmetto/corn silk/pygeum/zinc formula plus following a vegan, mostly organic diet. Often the pesticides and steroids in the non-organic meats, dairy, and produce are what lead to an enlarged or diseased prostate because they mess with your hormone levels. Also, the pesticides and other chemicals get lodged in your prostate, which is a small gland.
I also made other changes in my diet yet again to try to help my prostate, based on all the stuff I've researched. Highlights include to especially avoid caffeine, alcohol, soda, chocolate, white sugar and white flour, orange juice, and any spicy food. These are bladder and prostate irritants.
I also started taking zinc and quercitin w/ vitamin C. Quercitin apparently helps to lower inflamation. Another important supplement for the prostate is selenium.
Sitting in hot baths for 15-20 minutes at a time will also help lower inflammation in the prostate. I did that for a few weeks. Prostate massage is also helpful if you can get it or figure out how to do it yourself (that is not easy).
In 2 months I noticed a great improvement in my prostate - the last doctor check about a month ago revealed that my prostate had gotten softer and smaller from when I started. Alot of the pain is also gone now, especially in my right testicle. I would say most of the pain though was from the pus which was in there and has since come out on it's own, hopefully as a result of the methods I have been following.
Also, I also have to tell you that if you are or have taken antibiotics for any length of time, you really need to take a probiotic to replace the good colon bacteria that any antibiotic kills off. Without replenishing this bacteria properly, you will end up with more health problems soon down the road, such as Candida/yeast problems, constipation, fatigue, foggy brain, and many other potential symptoms. had to find this out the very hard way over the years. I now take a capsule called Primal Defense, it is the best probiotic I've tried. It's available in any Vitamin Shoppe catalog/store. Antibiotics are sometimes necessary, but unfortunately no one tells you that in addition to killing the bad bacteria, they also destroy the good ones that your body needs to function properly.
If yours is really a non-bacterial infection though, it should benefit greatly from any of the things above that lower inflammation, like the diet changes, supplements, and sitz baths. And it is important to ease up on any sexual activity, that can irritate the prostate too when it is already inflamed.
