A sudden rise in temperature (thyroid, blood, sore, doctor)

[Origin of Symmetry]

I had a very stressful day this Friday. It seems everything went wrong. I felt pretty well in the Friday morning but found out that my temperature rose up to 39C in the Friday evening. During the Saturday evening it was up to 40F. I was shocked since I had no signs of flu like sore throat or runny nose and still don’t have them now. The question is if stress alone could rise your body temperature that high? Today it is still high and around 38F.

I’ve been on a low fat diet recently. Get my weight down for several pounds. I guess it maybe a reason why my body was susceptible to some unknown disease.

I’m really puzzled as I have never experienced such a sudden and high temperature rise in my life without a reason.

What kind of blood and urine analyses should be taken first to find out what kind of disease one has in such cases. I guess it can be anything since there is no any symptoms but very high temperature.

Your doctor will know what kind of tests (if any) should be taken first, second, and next. Any time your temp rises to 104 (40C) you should consider it an urgent matter (even if it's not an actual emergency) and get to a physician that day.

initial reaction would be that if you have an indicated temperature of 40c, but you don't feel unwell, your thermometer is broken!

In theory yes. In practice let's put it this way. 1) Many employers don't welcome sick leaves. 2) You have a hope that temperature is going to get lower in a day or two, it is just a flu that goes by eventually.

Any symptoms besides fever? Fatigue, sweating, nausea...?

Flu does not likely come with fever and no other symptoms. The opposite: sore throat, fatigue and no or low fever would be more likely. Cold vs flu chart.

Being severely dehydrated and being in the hot environment can cause heat exhaustion (tiredness and rise of temperature toward 40 C).

I've not heard so far that anxiety alone could result in 40 C.

Viral pneumonia, hyperthyroidism, pheochromocytoma, fish/shellfish poisoning...these are some random causes of hyperthermia.

my husband had that once; woke up in the middle of the night with a 39C fever. Spent a day in bed with it and then the next day just weak and recovering, and that's it, we kept expecting him to get other symptoms but never did. Still don't know what it was, just a mystery virus I guess.
