Why did my mother go to the hospital with chills and the doctors found nothing wrong with her?

I arrived at thie site when wondering why I was getting intermittent chills mostly in my upper body and arms, and found that someone else had similar synptoms. I guess I'll have to see the doctor if they continue. I wondered if it had a physical underlying cause.

I get episodes of the chills in my arms mostly. I am dressed warmly and the temperature in my house is 70.6. The episodes of chills have been coming and going throughout the day for several days. .

update. Mom was fine but at home Monday. Dr. called on Tues. She test did reveal a urinary tract infection after all. She is on antibiotics for it now.

The 77 degrees was not referring to her temp but the room temp. Her temp checked out normal.

It was a warm day. Inside it was 77 and she was dressed warmly with a sweater too. It was above 80 outdoors. It was she visible shivering that worried my Dad. The episode passed before anyone at emergency really looked at her. Never the less it was several hours before she left.

sounds like its me ! i get low grade fever and i do freeze . my back would stiffen up , the only way i can get warm is to get in warm-hot water tub to thaw me out from the inside of my body .
there is a reason for her to be so cold . make sure that the house is warm and no cool air blowing on her . i know people have the air on during the summer and in the winter time the house is not warm enuff . i feel for elders cuz i do get cold ,
pa and i are comfertable cuz i do have an old womans blood . whenhe first moved inw ith me , he was scared that my house be too cold . i told him he doesnt have to worry cuz i can not stand begin cold .
keep her warm my dear ....

That is a low grade fever, Did they send her home? And the elderly are always cold not enough blood flow. The doctors didn't find anything?

Well for one thing the normal body temperature is supposed to be 98.6 so if she is only 77 degrees, then she IS cold I would say. I know I would be.
