I've been having a low grade FUO (fever of unknown origin) for about 9 weeks now, along with major fatigue and brain fog (I've been off of work the entire time). It started with a flu/upper respiratory infection that was VERY bad. I was given antibiotics which cleared up my sinus pressure/congestion, but the fever and fatigue remain...
This lead to a chest/abdominal/pelvis CT scan. We didn't find anything, but a single thyroid nodule. My doctor says this isn't the cause of my symptoms, but now we have to follow up with this too. I had an ultrasound today, showing one nodule at .97cm x .8cm x .7cm. The tech commented to me that they'll probably want to biopsy it because of the large size and because there is only one nodule. I haven't heard from my doctor about it yet.
I'm really scared of the biopsy. It terrifies me. I'm also frustrated because I feel like this is just a rabbit hole we're going down, meanwhile my other problematic symptoms (fever) are being ignored.
My TSH and free T4 are normal (TSH = 1.68 in a range of .4 to 4.5 and free T4 = 1.3 in a range of .8 to 1.8), btw. The only abnormal blood work I've had in this enormous, extensive workup is a slightly elevated CRP (.4 with a normal range of 0 - .29). Tested negative twice for Lyme, mono, CMV, etc. Infectious disease consultation was fruitless.
I'm supposed to see a rheumatologist for the fever, but they can't see me until March 30th.
Any experiences with biopsies? I'm afraid they'll want me to do this. Can't we just monitor it for growth? I'm scared this will turn into a thyroid removal surgery, and that my fever will still remain in the mean time...
"Tested negative twice for Lyme, mono, CMV, etc. Infectious disease consultation was fruitless."
Bartonella can cause FUO (as well as fatigue, brain fog.)
What lyme test did you have done (which lab)?
you might want to look deeper into the lyme/bart arena. An ID Dr. isn't the best for that.
