Hello I have a question. For about 3 weeks now I ve had painful urination. The funny thing is that I get a burning sensation only after I urinate. I drink lots of water, no alcohol, not a single drop nor do I smoke. I m 21, yes I don t a drink or smoke, my primary care provider said it could be an STD that Is causing this. I was tested for chlamydia, syphilis, and gonorhea, all negative. Three urine cultures, everything normal. No genital warts. My prostate was also examined and everything is fine. I was given azythormycin, doxycycline, a shot of penicillin, and pyridium. Nothing helped. I saw a urologist and all I was a diagnosed with was dysuria. I m worried and I do not know what is causing this problem. Do yall have any idea?
