I am worry about Syphilis

Hi, I am 29 and male, about two years ago I had sex with stranger girl. 1 month after sex I have just feeling swollen glands under my arms and darker point on my penis, but that was not sore. I can't remember how long after that maybe 2 months after that I had few circular points with white skin border around them. and those are dissappeared after a week. I had no more problems until 4 months ago I had sore throat for more than 1 month. whith that or a few days after sore throat I felt swollen glands under my arms and neck and over my legs and acnes all around my body but dissappeared after 2 weeks.
2 months ago I flet hard dizziness and noise or ringing in my head and I still have them right now. 2 months ago I got full std test included RPR Syphilis blood test and result was "negative-non reactive" for syphilis and other results were negative. my question is about my latent test, is RPR Syphilis blood test accurate after about 2 years?
should I be worry about my symptoms?
what is this annoying dizziness and ringing inside my head?, I visited ENT doctor and he said you have not problem in your ears.
Please help me I am so worry. I feel I'm dying.
excuse me about my bad english.

you have no reason to doubt your syphilis testing.

none of your symptoms seem std related.  continue to follow up with your doctors as needed.

Thank you for your Answer, but I am worry about my latent test. test after 2 years. I am worry about "false negative" results.
and this dizziness and ringing ears are very annoying.

your worrying is needless. if you can't move past this fear on your own, seek out professional counseling /therapy for it. It isn't healthy to have this worry for 2 years.
