inconvenient pain

Well, Yesterday I was walking Audrey to her preschool house (it's a 1930's farm-style home that has been a preschool for many years). This has been a killer winter with snow storm after snow storm. There was a recent ice storm that has everything covered in a thick sheet of ice. So I was holding Eliza in one arm and had Audrey by the hand and we were being so careful not to slide and fall. Audrey was anxious and pulling on me. I was counter-balancing and telling her to stop pulling. It's not what you are thinking I am sure. At this point I did not fall or hurt myself. Strangely enough it was when I got safely inside that I put the baby down, helped Audrey put away her things in her cubby and found that when I went to bend over and pick Eliza back up that my back suddenly went into spasm. I swear, this has never happened before. I feel like my body is falling apart. My back has been killing me for the last 24 hours. I can hardly lift the baby now. I went to see a physical therapist and he tells me I have a week glute muscle back there and I need to ice my back and do leg lifts to strengthen this butt muscle back into health and save my back. This could also be the reason my tailbone was so painful during pregnancy. I am getting old and falling apart! It's time to work this old bod back into shape I think...
