My husband is breathing heavily--has a cold virus--his temp is just over 102. Last night it was the same thing, about 8:30 pm he developed a fever that went up to 102.8. Then it goes away. This has happened to him in the past, usually in the winter. No one can say why he gets these fevers. He s not in good health. Very weak. Anemia. Low wbc. Constipated. Poor muscle tone. Has trouble with balance and walking. He has been diagnosed with interstitial lung disease but hasn t followed up with the doctor on that.
