<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 66 year old diabetic female who is in ketosis. I have been having back pain lately and am wondering if the two are related. I take a magnesium supplement. My blood glucose has gone from 296 to 115 fasting since drastically lowering my carb intake. Ive lost 15 pounds so Im having great results but my back pain is causing me to limit my activities. I would appreciate any advice you can give me. Thank you.  <response>: For my 66-year-old diabetic female on low-carb diet having excruciating back pain, I would have the following advice; Backache may be unrelated to the diet changes. I would first consider ruling out calcium deficiency andor osteoporosis. Secondly, would like to look at serum electrolytes as the pain may be due to muscle cramps. I hope you are taking adequate fluids. If I can rule out the above-mentioned suspicions, then would have my patient evaluated alongside with an orthopedic neurosurgery team to look for any organic cause. You can discuss the above options with your caregiver. I hope the above information helps you. Thanks for writing into Chat Doctor. Have a wonderful day.
