<s>[INST] 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.  I've lost 15+ pounds so I'm 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. [/INST] For my 66 year old diabetic female on low carb diet having excruciating back pain, I would have the following advice; Back ache may be unrelated to the diet changes. I would first consider ruling out calcium deficiency and/or 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 orthopedician/ 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 healthcaremagic. Have a wonderful day. </s>
