I have been sexually active for a year now with a mutual monogamous partner, with my last sexual encounter being about 2 weeks ago. Just recently, about a week ago i started feeling my urine was hotter than usual. The sensation of peeing it out was not really painful, but i can feel that it was hot, and when i touched the urine, it was indeed. I ignored it after a couple of days, then from there, i began to feel a tingling/itching in the tip of my penis(urethra). It is like a constant feathering that doesn't go away, although it is nothing painful it is a constant bother to me, and i actually have a hard time sleeping with it. Apart from that, it also seems that sometimes when i urinate, i feel that not all urine comes out, and also the constant tingling sensation i feel from the tip of my penis sometimes fools me into thinking that i need to urinate, but end up empty when i go to the toilet. So lately, i have been taking urilacin since it may seem like a common symptom of UTI(urinary track infection), and i also had a urinalysis done. The results all came back negative for any signs of kidney stones or other problems. After a couple of days of taking urilacin and drinking plenty of water, i have been feeling better, my urine doesn't feel as hot anymore, and the tingling sensation in my urethra is slowly going away. But i am still anxious for any possible std infection like chlamydia or gonorrhea with similiar symptoms, even now that i am okay and symptoms are likely to dissapear.
So my question is, could i have acquired chlamydia or gonnorhea, since my urinalysis have ruled out any sign of kidney stones? On a side note, i do not have any other symptoms like swollen testicles, discharge or anything like other than a slight burning sensation when peeing and the tingling in the tip of my penis.
I don't know if i should still have an ultrasound done to check for any kidney stones or any crystals in the process of formation even if my urinalysis is negative for any sign of it. I also recently had a gout attack in my heel because of my high uric acid. I also am unsure if i should go for a costly std test for chlamydia/gonorrhea, which also needs to be approved by a doctor's prescription first here in my country.
