sneaking up on a person

It is funny how sinus infections sneak up on me. I have had yet again an infection sneak up on me and I don't go to the Dr until I am miserable. Last night, I went to Urgent Care and got some antibiotics prescribed to me and now, sigh, I am starting to feel a bit more normal. I really need to make myself be more alert to the warning signs. I am not a very nice Mommy when I feel so sick and headachy - I tend to be snappish. Poor girls.
