My toddler has hand, foot and mouth. She's been sick about a week and I was fine until this morning. I woke up with a horrible headache. It felt like bad sinus pressure, so I took Allegra and Sudafed since I suffer from allergies as well. My symptoms were untouched. My neck is stiff and sore, feel feverish but my feet are freezing. And super tired. I also have pains in my back, not in the middle but slightly off to the right, but upper and lower back. does this sound like VM? Couldn't get a dr's appt til tomorrow.
