So I'm 15 and I had sex with a 23yr old women and I went to the doctor and got checked I had a uti and chlamydia I got treated for it but it seemed like I had left over symptoms and I went back to the doctor they took blood and gave me powder with 4 tablets and shot in the butt but before any of medication they gave me they said I tested negative to everything then they gave me those meds but even after that I still had symptoms so I went to the clinic and got checked they said I tested negative to everything again but I still have a mild burning when I don't drink enough water which is weird because it's a shorter time then a normal person not drinking water and I also have a tear on my meatus from the oral she gave me I guess her tounge piercing cut it and I also have the horizontal cracks on the head of my pens the Doc ors said they were not related to any and but I'm having second thoughts please help me
