Strange penis infection symptoms

It started last November. I developed something that seemed to be a minor fungal infection. Shiny cracked glans surface and cracked skin around the foreskin. Nothing major. I tried removing it for a month with creams but it didn't work.

In January, I went to donate plasma. Never thought about consequences in my penis. I donated on an evening. That same night, I quickly started having fever/flu symptoms. Achy body, chills, joint pain, weakness. I knew something wasn't normal. Went to bed. Next day those symptoms were gone, however, after getting dressed, I felt a weird sharp pain in the head of my penis while rubbing against my pants. I started inspecting and found a lymphatic vessel severely swollen. The end of that vessel wrapping around the base of the glans, was causing the pain. Later that day, my whole penis started swelling getting worse by the hour. Next day, it was the size of an Idaho potato, with a clear discharge from the tip. At that point I assumed that any kind of infection that I still had, proliferated and colonized my body after my immune system went down from the plasma donation. That second day with my penis swollen I almost fainted on the street. After that I decided to go to the ER. All STD tests came negative. They gave me a shot and 2 antibiotics to take for 2 weeks. The swelling slowly subsided, but NEVER completely.

That is my problem and concern now. It's been almost a year and my penis is always retaining water under the skin throughout the whole shaft and tip of the head. The tip of my penis is always red and swollen around the opening giving my glans a cone shape instead of the dome shape that had before. Plus, the water holding under the skin I know is not normal. I know I have something. Is hard for me to go see a specialist and further exams because of money. But if anyone has any idea of what this could be I would really appreciate it. Is frustrating, embarrassing. I've tried different hygiene methods, even flushing the urethra with hydrogen peroxide. Other than burning and becoming foam, it doesn't make a difference.

Although I have noticed that if I overdose vitamin C at 10 grams a day plus a claw of garlic every day, the swelling really decrease. But it comes back as soon as I stop the vitamin and the garlic. I know I need medications and a diagnose.

Thanks everyone!
