<s>[INST] 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. [/INST] Hi, Welcome to Chat Doctor. After going through your query I think you are suffering from muscular pain due to injury. Treatment of it is rest and analgesics (diclofenac three times a day after meals). Sometimes strong analgesic(such as tramadol three times a day after meals) is required. Omeprazole before meals prevent acidity caused by analgesics. You should rest as far as possible as in this condition muscles need rest. It may take a week time to complete relief. However, you can get spine and chest x-ray done to exclude fracture. You can discuss with your treating Doctor about it. I think your query answered. Welcome to any follow-up query. </s>
