question: I have been running a fever for nearly a week. (started last Thursday 1/19) at times as high as 106. I know that sounds crazy - but it is accurate. I am using a hospital grade thermometer (Exergen $389)Anyway I went to ER when I developed some pain in my right flank. After taking chest x-ray, sonogram, urine dip, blood draw they couldnt find anything wrong. I think it was just body pain from the fever itself. All the docs tell me is it must be a flu virus. I have clear sinus and lungs, no pain with urination or BM, no diarhea. I am sensitive to molds. I used to get sinus infections when exposed. A few years ago I found out some of my food sensitivities and eliminated them from my diet. I havent had chronic sinus infections since them. Do you think this could be an extreme allergic reaction? I really need to figure out what is happening here. Im pretty weak.
