I am a male of 55 years of age and suffering from diabetes for the last 5 years. I am taking k glim 1 m forte morning and evening and my sugar level is around 180-200 after breakfast. For the last 2 months I am feeling a burning sensation (or as if someone is breaking my nerves) on the outer side of right knee joint. And now the same problem is occurring on outer side of left knee joint. I just want to ask whether I am going through the stage of nerve damage. What is the treatment and precautions. Please help.
