Allergy, symptoms similar to son’s barley allergy.
Legionnaire’s disease from office air cond system poor filtration?
Sounds like a potential toxic thyroid condition. Do not assume thyroid blood tests are accurate, see an endocrinologist. My family doctor about killed me relying on routine blood work.
Any foreign travel by you or close ones in the past few months or peers in the same work environment.
Malaria?
It sounds like the non-flu flu I had last year starting in January. Took me 8 weeks to get rid of it. The doctor told me I didn’t have the flu, but simply a “virus” which I probably got because my immune system was low due to stress.
Symptoms: Alternating chills and fever, fatigue, rash on chest and face, blisters on hands and arms, cough, sore throat. No nausea though. A couple of times I started feeling better but then relapsed.
Malaria?
Sounds like Lyme disease along with co infections to me. Unfortunately, the tests are not very reliable and finding a Lyme literate doc is next to impossible. Oh, and less than 50% get that bullseye rash that could be a giveaway to diagnosis.
These guys can help too, beat the reaper:

Something similar happened to me one summer while I was in college. Fever, chills, writing was a chore and my gait was almost reduced to a shuffle. Back to normal in a couple days. Never experienced anything lik it since.
I figure it was a flu virus of some sort.
Not sure what you do for a living, but if you meet a lot of different people during the day I would take the usual precautionary steps to avoid catching the flu.
I would also get a second opinion from a different physician.
Have you had your thyroid checked? Underactive thyroid leads to chills.
Get checked for Lyme. Had a friend undiagnosed for years. Also check Menangitis. Has also happened to another friend undiagnosed.
I have lived through what you are describing. I had a hernia below my navel that was about 3” long. My intestine would pop out and then back into place, and it was bruised pretty well and that would be the symptoms you are experiencing after the fact. I would go to the emergency room, they would do all the CT scans contrast etc, and no dice. They did “exploratory” surgery and found it.
Something to think about.
Sounds like Malaria to me. Have you been anywhere tropical recently?
There are several infectious diseases that are rare in the US and very difficult to diagnose because most physicians are just not familiar with them.
Also, cancer could be a possibility.
You need to get a thorough check.
Menopause
Have you stayed in a Holiday Inn lately?
Read up on what ulcerative colitis and microscopic colitis are and their symptoms. See if you can eliminate it as a cause. If not it may be a suspect. Also read up about leaky gut (permeable intestinal membrane). Then look up FODMAP foods to avoid (fructose, dairy, short chain food molecules). If you do better avoiding those foods that may be a place to start. Or try taking calcium (but not calcium oxide). That would likely make you a bit constipated but may also close up any leaky gaps in your intestinal wall cells. Colitis can go on insidiously for years and doctors seem to be blind to it. Another question: do you simultaneously have nasal histamine? That may be a marker of colitis when undigested food gets through the cracks in your gut lining and get into the blood stream creating brain fog, fatigue, drowsiness and dehydration. If none of the above, then eliminate colitis as a possibility and explore other causes.
My wife and I had 2 rounds of similar scourge in late Dec and January. We picked it up at a grade school where we eat in the cafateria for a Christmas concert.
