Hi i'm 22 years old, height: 5.5 weight: 52Kg and have a burning sensation quite often not necessarily only when i urinate, but when i just carry on my daily work as well. I have irregular periods and its typically PCOS, but I have taken medication and its much regular now. I only have sex with my boy friend and he does only with me as well. intercourse has been painful lately where i get a pelvic pain & burning sensation with it. what do u think it is? and what kind of doctor should I go to?
