What Causes Pain In Lower Abdomen And Penis?

Hello, I have been having a slight pain coming from inside my penis for a little while now that has gotten worse. It sometimes feel like something is moving in there. In addition I have developed a yellow spot just right of my left pupil and recently have started to get pain three inches from my belly button and lower right abdominal pain. I have no discharge and have got tested for chlamydia and gonorrhea twice both negative. I had some swelling in random parts of my body before the side and abdominal pain started but dont know if its related. The first symptom was the pain inside the penis but it was a small pain at first started after I had unprotected sex in the end of September then I developed the yellow spot in my eye as well as a yellow/reddish line going across my eye. I have no problem with my vision and my optometrist said it was nothing. Next came the random swelling which started with a few on my neck and right arm then when they went away new ones came on my left arm and then my neck again. I was giving bactrim pills which help to keep them down and some type of steroid shot to my buttocks when swelling got bad. I have gotten a few minor swelling since but nothing as bad as before. Since the pain inside my penis has been worst, it went from being a once a few days to a everyday pain and now with the side pain im really starting to worry. I have also started getting a slight pain right below my testicles. I have no pain while urinating or after ejaculation. Unless im sitting still the pain in my penis use to be unnoticeable but now I get sharp pains randomly no matter what im doing
