My Mother Aged 76 Yrs Has Been A Diabetic Patient

My mother aged 76 yrs has been a diabetic patient for long under medication. She is also under medication for filariasis and osteoarthritis. Fearing the possibility of her kidney damage we stopped giving her pain killers. Now she is unable to take single step forward and just sitting. We are only giving her diabetic, iron and vitamin medicines. Pls suggest how to help her walk again without support. Thanks!
