Prostatitis Symptoms?

[Calvinj97]

About 2 years ago i started to experience pain right in the centre of the perineum. It was a burning/tense pain. I went to the doctor and he gave me augmentin and it cleared up for the whole summer but returned the following september of 2015. I decided to leave it and see what happened as i'd had a testicular exam and my doctor couldn't see anything worrying. About 4 months later i went back to the doc and he gave me another course of augmentin, this time not clearing anything.

He then referred me to a urologist. I went and explained my situation in march 2016, did a urine test, had a cystoscopy yet still there was no sign of anything.

Here i am in January of 2017 with the same symptoms and more. I have symptoms of Prostatitis/Epididymitis. See Below all symptoms.

Started with
-Pain in perineum
-Burning Urination

-Green/phlegm like semen or ***
-Painful ejaculation
-Dry/Shiny penis head after ejaculation
-Red penis tip
