Hi I am feeling heat and pain in my left lower abdomen area and that too not Everytime only some times and I feel some tickling and burning sensation on my penis this is not like unbearable but I am worried about what's happening. Can you suggest me which Doctor I shouldsee and any help please I gave my full STD panel test and all were negative as I had unprotected sex last week I feel it's due to that something happened to me. I don't feel too much pain/ burning sensation but it never happened to me and I am worried why this is happening
