my aching back

I've been having different issues with my back since about school started in August. I thought it was due to all the new physical strain from working. And it probably is. I can usually take some Tylenol before work and am fine until I get home, not always, some days I am hurting a lot before the end of the day. I did have an MRI in October to see if there is anything new wrong. Nothing new. This weekend I really put a lot of strain on it. Doing too much in such a little time frame. Last night I took some of the heavy pain killers left over from my foot surgery, I'm thinking I need to do the same tonight. We are hosting a small Christmas party on Dec. 10th, thus feeling a time crunch to get the house decorated for Christmas and goodies made. (I'm not sure how much time or energy I'll have after working) Today I started putting away our every day decorations, so I'll be able to out the Christmas stuff out faster when P and J get it out of the attic. I ran out of boxes, so I'm not quite done. I also need to clean, but I'm thinking right now that will have to wait until at least tomorrow.
