Bactrim and ibuprophen

I took Bactrim for a urinary tract infection. After I had taken the Bactrim for two days I started having really bad hot flashes. Never have had them before. I was burning up constantly, all day. Sweating on my face and chest. Slight nausea and headaches. Some dry mouth. And just an all over feeling of being tired and not feeling well. I haven't read any postings yet about people feeling hot or running fever, but I really think this is the problem. After 3 days of constantly being hot and sweating, I felt like I was about to go crazy. So I have stopped taking it today. I hope it goes away quick, but I have read it can still take a few days for it to get out of your system. Has anyone else experienced the being hot from taking Bactrim?
