Hi,

sorry to jump on this post but I have been feeling the same symptoms for the past couple of months. Been going in and out of the doctors to see what is wrong with me but no answers. Everything is coming back normal which is good but doesn't explain the persistent low grade fevers. 
 

I am now pregnant and it's really worrying me about how it'll affect the baby. Spoke to the GP and said there's nothing to worry about. But I've not felt normal in months and it's starting to really affect my life.

has anyones symptoms eased and gotten better or has anyone figured out what would be causing low grade fevers?

Hello guys,

I am also suffering with low grade fever at the beginning it was mostly between 37.4 - 37.7 . It all started as a flu. (Normally my temperature goes down at night sometimes even 36.9) 

I am on the 3rd month with temperature and I basically don't have the flu symptoms anymore. 
I am currently only feeling weak and I feel when the temperature is high because I'm either shivering or just feeling my face is burning, no other symptoms except when I touch my stomach and belly I feel a bit of pain mostly left side down my belly) 

i had to go to my country as I was in the GP (for flu symptoms) I was on 4 different antibiotics plus steroids and my temperature was not going back to normal even after all this medications. In the emergency they've done blood tests CBC and inflammatory blood tests, all came back normal. 

After I went back to my country I have been soon sent to see an infectionist which sent me to do many blood tests. I've tested for STI including HIV, toxoplasmosis, ebbstein Barr, Citomegalovirus also done a throat CT and chest X-ray etc all came back fine. 

then I was sent to see a reumatologist for autoimune diseases, all tests came back fine. 

then I was sent to see a gastroenterologist, he send me to do the FIT test, which was way above the normal range (double) and Clostridium Diff. I first tested Positive for Clostridium GDH. 
the doctor then send me to do the mononuclear test for Clostridium, and it came back positive. 
 

I started the treatment, I was first prescribed 10 days of 125mg Vancomycin, my temperature only started to get to 37.0-36.9 in day 9 and 10. 
then the doctor changed my medication to Rifimaxin 3 times a day 2 pills, on the first 2 days my temperature stayed 37.1-37.0; on day 3 my temperature started to raise again. I was so scared, I called the doctor that evening and changed my treatment with Metronizadol 3 times a day. My temperature stayed between 37.2-37.4 and on day 6 my temperature started to raise again 

I am on Vancomycin again, waiting to get the colonoscopy. 

i am also considering to ask the doctors for a recommendation for a full CT/MRI. 
 

please let me know if anyone found the cause of the persistent temperature.
