my mother is 87 yrs old, obese with high blood pressure. two weeks ago her legs started to swell. She is on water pills, but her doctor gave her a stronger water pill, this morning her left leg is twice the size of her right leg. I called her doctor and he told me to increase her water pills. My mother is not active at all, she sleeps most of the day and will not walk. she only walks to her bed and to the bathroom. She was like this before her legs started to swell. She refuses to do anything for herself. Should I take her to the hospital?
