As your mother is diabetic and has the pain of food I will advise to first control the blood sugar levels by medical prescription provided by the diabetologist
Along with thing start doing exercises as it will help reduce the blood sugar levels, improve Muscle strength, improve metabolism
and reduce weight as well.
For the pain in foot, use the hot water tub to dip the feet and then try picking up the marbles from the water with the help of fingers of the foot.
This will help improving muscle strength and also reduce pain. In my clinical practice of 12 years, most diabetic cases with foot pain are taken with utmost interest as reduced metabolism due to Diabetes
can lead to fatigue
and weakness of the muscles.
A combination of drug therapy and exercises have shown a positive response.
Hope I have answered your query. Let me know if I can assist you further.
