My menstrual cycle ended on 7th. I had an intercourse on 8th, and frm the next day morning, I was having high discomfort while passing urine. I presumed it's a minor uti and started taking medicines combiflam and oflox-200. I took a smoke yesterday, and since then my upper stomach has been paining so badly, like something is choking up inside. I feel like vomiting, bt it doesn't come out. Im worried and even now I have issues while passing urine, or it keeps paining and I hav the tendency to keep on going to the bathroom.
