5 Days Back I Had A Little Bit Of Food

5 days back I had a little bit of food poison during it I had feelings frequent urination and each time I urinated less and after some anti biotics my food poison got fixed but I was still having the frequent urine problem then I had urine Dr test and it showed something written like mucus thread and on the same day I felt pain above my penis so I went to the doctor with the report and he said I got a little infection so he gave me some tab and anti biotics and and a syrup for health urination so on the same day I felt trouble urinating as in I need to go urinate but my urine didn't have any pressure and I felt like I had to push to urinate so is that common while infected as in difficulty urinating it feels like its coming low quantity and I have to force it out
