Medical malpractice? Need advice.

So, I’m currently in Italy doing my postdoc, and honestly, the healthcare bureaucracy here is a nightmare. My insurance expires tomorrow—so now I have to hand over my new contract to the police, wait several days for their approval, and then take that confirmation to the local health clinic...

The issues actually started about eight weeks ago—trouble urinating and just feeling completely drained. A swab came back positive for a mycoplasma infection in the urethra, but while I was stuck waiting for those results (for more than two weeks 😢), my lymph nodes started swelling up. Once they finally gave me a diagnosis, they put me on erythromycin—2000mg a day split into two doses—which stopped the urinary issues and slightly shrunk the nodes.
But I finished the antibiotics last Monday, and just a few days later, the lymph nodes are acting up again—now they're swollen in my groin, under my arms, and in my neck. I’m at a total loss. I’m seriously considering just quitting—I’ve got three months left on my contract anyway—and heading back home to the States. Between this bureaucratic limbo and feeling progressively worse, I don't know what to do. Is swollen lymph nodes enough of a reason to hit the ER today, or should I wait?

Best,

p.s. I am panicking here and would truly appreciate any advice from a doctor out there.

I posted an update on my status last week. Now, I’ve got these lymph nodes swelling up in my neck—really aggressively—and I’m feeling incredibly weak. I’m honestly considering flying back home to the States to get treated. How urgent is this? I have an appointment scheduled at the university hospital with my doctor this Wednesday, but my insurance coverage expired today, and thanks to all this endless red tape, I have to wait about a week for the extension to go through.

I know it might turn out to be nothing, but can someone just give me some advice—would you guys head back to America for something like this?
