Few weeks ago i started taking some high strength multivitamin & mineral, i notice each time i urinate my urine turns to a solid yellow colour, i was a bit worried but got told it's normal when taking a high straight multivitamin. Just few days ago i woke up in the morning went to the bathroom to urinate, while urinating i felt  peperish sensation just at the mouth of my penis it lasted for few minutes then stop. Since then i have been feeling the burning sensation after urinating and i also notice each time i drink lemon water it help in calming down the  peperish discomfort, i don't have any pain during urination and there is no blood in urine and i have not had sex for 18 months. So what Could this be, an infection or as a result of the multivitamin I'm taking or a tear inside the mouth of my penis....Do anyone have an idea please.
