What is wrong with me? Is it flu or a fall or the cold from hell?

I took the kids sledding yesterday and I fell on har ice several times and got some nasty bruises. I woke up today in serious pain (It is horrible trying to bend or straighten my legs) BUT I also am congested, my throat hurts, my ears hurt and my head hurts. I feel chilled- but I have no fever. I just feel uuuugggghhh.
