I have a strange question and wonder if anyone else has experienced this symptom. I have always had a very low immune system but I can be seriously ill and NOT run a fever like normal people do. I rarely run a fever. Maybe once a year if that! But as a child I ran 104+ every two weeks or so. As I got older, I of course became sicker with lupus, heart valve disease, fibro, lung disease, hashimotos, anemia, arthritis...ect.....you know..on goes the list..So here is the question....When I get an infection now, I develop these horrific cold sweats rather than a fever. I'm freezing cold but can not cover up because it makes the sweating worse. My skin and face turns beet red and it will last for hours or days until I get on an antibiotic. And the pain in my joints and muscles are at their worst!! If I take Tylenol or Ibuprofen, I will sweat terribly within 30 minutes just as if I was coming down from a fever. My body temp at those times are usually 94 degrees!! It is by far one of the most uncomfortable symptoms I have next to chronic pain!
