Very occassionally (maybe once a year, if that often) I feel awful and slightly like I have a fever, but my temperature turns out to be low. If we are considering a fever begins at 100 degrees F and 98.6 is normal, this is a 1.4 degree change; I will often have a temperature below 98.6 at more than a 1.4 degree change (97.2)normally in the 96.5-96.8 degree range.
I am using a digital thermometer under the tongue for these readings. I have a normal temperature range when I do not feel sick. My father (56) also gets this on occassion. I do not have chills but I will feel uncomfortable and flushed, often have a headache, and feel lethargic and just not right.
Do you have any suggestions as to what this might be?
