Hello, Doctor... My mother is 89. In the past 2-3 weeks, multiple health problems have resulted in quite a drastic decrease in her mobility. She has been sitting most of the time, and her feet, ankles, and legs have been swelling so much in the past 3 days that she has been unable to get her compression socks on. Last night she was unable to sleep due to severe pain in the lower extremities, and she had to call my brother to help her, as she was unable to sit up by herself (this is not typical for her). Do you think she needs to be evaluated for deep vein thrombosis, and if so, what would that evaluation involve? Thank you so much for your time and expertise. Mickey
