Hi welcome to the health care magic According to history it seems to be acute urethritis or acute urinary tract infections... First investigation that has to be done here is urine routine microscopic examination If pus cells and bacteria present than suitable antibiotic needs to be started like cefixime.. If feasible antibiotic started according to culture report USG can be done to look for kidney affection, cystitis etc... Avoid excess spicy foods Drink more water Cranberry juice will be beneficial Take care Consult nearby doctor for examination with keeping these in mind
