I am so sorry Anika is not getting better. I know how stressful this is for you. But know you are not alone, your PT family is here. Unfortunately, most of us have been there and know exactly what you are going through. It helps to have people behind you that can relate.
I will be thinking of you and Anika and hoping she will at least get fluids in her until you can get the ultrasound and find out what's going on.

Hugs to you and gentle hugs to Anika.
