Hi, I am an American Board Certified Neurologist and I am very glad to help you with your health concerns.
It is better she is shown in the emergency room asap because her swelling is increasing and from the lower leg now spread to the thighs. While she certainly needs an ultrasound to rule out any blood clots in the leg veins however it needs to arranged faster because her symptom is worsening. Also there may be other explanations for the leg swelling. There are myriad medical conditions that can cause rapidly progressive swelling and considering the swelling is worsening fast so it is better she gets investigated very soon. So in this regard it is better if she can be shown in the emergency room so that she can get all the relevant investigations faster. Another issue with waiting for the outpatient ultrasound is if the ultrasound test comes normal then she still needs other investigations to look for the cause of the swelling so by seeing doctors in the emergency room she can get an ultrasound as well as any other relevant tests and all these can be arranged very fast in the emergency room, so instead of waiting for the outpatient ultrasound it is better she is shown in the emergency room asap.
