To bend or not to bend?

So apparently I did hurt my back with all of my falling down and sliding yesterday. I had a general body ache yesterday that got worse as the day went on, but I assumed it was due to my cold. This morning when I woke up I had muscle pain in my back. The more the day has gone on, the more it hurts. Now I'm at the point where I can't stand straight up. I've tried Aleve, the heating pad and Icy Hot. The only thing really helping is the Icy Hot. This really sucks. I hope it's better in the morning so I can go to class. Otherwise I'll be going to the doctor instead.
