Over the last 1-3 years I have been living with 99.1-99.9 degrees fever.. When I have a spell, my cheeks feel really hot and then I take my temp.. sure enough.. it is above normal. I have had cbc diff. no infections, urine checked out fine, I have been checked for HP BA and C and AIDS, LUPUS, RA Ankelosing Spondalitis. Cat scan of the abdomen, chest and pelvis looking for Lymphomas... I had diverticulitsi in 2012 and Ulcerative colits, so I thought this was my problem even though not having any bathroom problems consistant with the fever.. although I do have IBS.. Gastro today told me that he was 80 % sure that it is not UC or chrohns.. So now I am at a loss and keep searching. I feel so crummy and no energy... Getting ready to tell conventional medicine to take a hike and start with a Nutritionist/Naturopath and keep journaling. I too sometimes feel like I am going crazy.. Everyone wants to just tell me it is Hormonal...42 years old...I am so sick of hearing this..
