my daughter is away at college and just called. This morning she started feeling nautious & dizzy, throughout the day she s unable to hold down food and has been vomiting. This evening, her achiness is turning into more intense pain, she is experiencing numbness in her calves. At first I thought it was flu, but the numbing in calves has me stumped. Should I send her into the ER? I m five hours away from her, so I m unable to see firsthand her symptoms
