question: I slipped in the bath this morning from a standing position. Came clattering down on my back. I was very winded and had difficulty breathing initially. I now have a bad ache in my back over the lower rib cage. I have no numbness in legs or arms. Should I lie flat or move around to keep the muscles active. I am using an ice pack at the moment. I am 63  and weigh 9st.I have controlled high blood pressure 5mg enalaprol a day and mild asthma.
