My mother was diagnosed with diabetes last year where her sugar levels shot up to 350. But it got under control later. She has been taking medicines regularly (Glimisave M1 before and Volix trio 2 now). She started suffering from skin allergies later which aren't cured yet even after months of medication and lately she's complaining of acute ache in her left arm which has spread to her chest also. We consulted a diabetic expert and then an orthopaedic too. They recommended a few exercises but they seem to make no difference. A few of our relatives suffered from similar problems and now their hands do not move at all. Please give a curable solution. We're worried.
