question: Hello doctor, Ever since I had started being sexually active last year, I have been getting frequent UTIs. I had been having a UTI for a long while. I got it checked last week, and I was prescribed Sofilex for five days. The UTI got better, and everything was fine for about a week, and today it started to hurt again. I am peeing frequently, and I feel pain in my lower area. Last night, I was feeling quite sick. I had a headache, nausea, and pain. I was not sure if this was because of the UTI starting up. But, this morning it had definitely started. I am still sexually active, and I know that sex can trigger infections. So, I clean up thoroughly after sex, as advised by my previous doctors, and according to what I have read about its prevention. I make sure it does not get too rough or unlubricated. I just want to know why the UTI keeps occurring and what I should do differently, to stop it once and for all. Is there a different type of medication I should take? I read online that there is a type of medication to take after sex. Is this going to be helpful? If it is possible, may I get a suggestion for which medication to take? What to do next, to make the UTI stop from recurring? Are there any medications or lifestyle changes to me made? I hope to hear from you soon.
