I am so worried today..

I am just so worried today for the reason that my younger sister went to the hospital to get her swollen feet checked by a doctor. My brother accompanied her since I can't make it because I have to look after my daughter who is just 3 years old. It just began to swell this Tuesday and  she still went to school that day despite the hard  time walking due to swelling. . It just started with an open wound that I think later on was infected. I just hope and pray that everything will be alright and there is nothing to worry about since it was just little infection and can be treated with prescribed medicine. I am still waiting for them to arrive and a bit nervous since I have no idea what was really the reason why her wound was infected and got swollen.
