Hi, monday evening 4 days ago, i suffered a burn to my foot ankle and calf from a fire. I went the the local ER on Tuesday... They prescibed me tramadol for pain and silverdine (sp) cream to put on the burn. Early this morning (midnight- 1am) i started feeling really bad with a fever of 101.8 and chills. All day today ive felt cold and just recently developed a fever again of 100.1. I also recieved a tetanus shot in my shoulder and its very sore... I just want to know if my side affects are normal, or should i return to the er?
