Help me out of this place!!

[petebt18]

3 months ago I recieved minor risk (very minor I am told) sexual contact with someone after 10 years of very happy marriage and 18 years relationship. I had too much to drink and and did somthing out of character, i am ashamed and far from proud. At 4 weeks without any symptoms I went to a private GUM doctor. He did tests for STD and HIV, said they were not required but to put me at ease. He put me on antibiotics to be iron clad whilst my resulst were due back. I have been back and had a total of 4 STD tests (and total of 4 antibiotics), all clear over the course of the last 8 weeks. I have testicle pain,comes and goes, not there at night or when I have a drink in the evening, mainly when sitting. I have pain in penis at times and what feels like second UTI. My doctor tells me it could be in my head. Could this be? It all feels so real. I worry about it 24/7, it is the first thing i think about when i wake up. Can anxiety create feelings of pain in the body. My wife and I tell each other everything so I feel so alone in this for the first time in my life, I feel like I am at the bottom of a very drak hole. Any advice would be very helpful.
Thanks

Easy answer if you had a involved conversation with someone and did not think about HIV and you did not have these imaginary pains injected by your brain then you know the answer.

Look up pelvic floor muscle dysfunction - it is stress caused and can produce your symptoms

I wager 99% this is it - have seen it so many times
