I started taking Bactrim for a UTI on a Monday night. Tuesday morning I work up with a intense headache I took the second pill that morning, by mid morning I started having pains in my left hand wrist, than having severe pain in my left leg making it very hard for me to walk, leading to fever and pain all over my body i.e., neck pain, lower back pain, joint pain I just hurt from the top of my head to the tips of my toes. I went back to the doctor that day (Tuesday) and was told I might have the flu after taking two flu test and both coming back negative I was given something for the pain and told to come back the next day if I did not fell any relief never the less I did not feel any better the next day in fact I was worse, I had a fever of 103.3 and climbing after returning to the same doctor for a third day and the doctor not having any answers for the way I was felling I, was advised to be taken to the ER on Wed and later admitted to the hospital and released with out being told what was causing me such sickness. It was not until the following week that I was told by my regular doctor that I was having an allergic reaction the Bactrim, it has been 9 days later and I still have swelling in my hands and feet and pain in my neck and legs. When will this end
