Prostate or nerve pain?

Hello,

For months I have been dealing with chronic pain, I’m in between appointments with a rheumatologist but looks like fibromyalgia? 

I have pain literally everywhere but something new is starting and it’s making me nervous... 

I’ve been getting bad spasms in my rectal area and really bad lower back pain on one side, today I started peeing and I had a horrible intents pain about an inch above my penis.. 

Does this sound like prostate? I’m on 25 which seems young.. could it be related to my current body pain and problems? 

Please help.
