I fell about a week ago and after going to the ER and having an x-ray taken, I was diagnosed with a chest contusion , aka- bruised ribs. Since then, I have noticed my stomach has gotten big. Looks to be swollen, no pain. In fact, I look like I am pregnant . I know I haven t been working out in the past week, but there s no way I could gain that much weight in a week. I was wondering if the two were related. I am a 44-year old female in good health. Had a partial hysterectomy over a year ago, so pregnancy can be ruled out.
