Bactrim and ear infection

I started taking generic Bactrim about 3 weeks ago for an ear infection. The first two weeks I had no problems, the third week I woke up one morning with one side of my neck sore. I thought I just slept on it wrong and didn't think it could be associated with Bactrim then over the next two days my neck became more stiff and sore it even hurt to touch. I could not move my neck at all without experiencing pain. Also I would get servere headaches when I moved my eyes to look up or to the sides. The sharp headaches would only last about a minute or so after moving my eyes. My arms and legs started to feel achy like when I have a fever. The third day after the first sign of neck pain I broke out in hives on my arms and hands. I stopped taking the Bactrim (because I found this site and similar ones) and two days later most of my hives were gone and my neck pain was noticeably less. Four days off of Bactrim and my neck is almost completely better and my hives gone. I will never take a sulfa drug again

This is my 3rd day on Bactrim. The side effects are horrible. I am taking 1 pill 2x per day for an ear infection. I am experiencing extreme fatigue, gastrointestinal upset, agitation and insomnia. I don't know how much longer I can put up with these side effects. I feel like staying in bed all day and just taking a shower and getting dressed makes me exhausted. I am 23 years old and thought I was really sick, so I ran a search on Bactrim. I would not recommend this drug to people. Ask your doctor for something else instead. The side effects with this drug are pretty bad.

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?
