Early this morning, she woke up with a slight burning sensation across the upper middle area of her chest. Later on, she felt a slight heavyness in her chest. It would eventually get better by evening time.
The doctors listened carefully to her lungs. They said her lungs sounded clear.
One possibility is she might be fighting off an upper respiratory infection. It's been going around here in the small ward where we are. There are no open windows here so it's hard to get real fresh air.
