Hi,
Thanks for posting your query.
Diabetes is a multi organ disease with involvement of almost all organs of body due to its complications.
Blood sugar both fasting and postprandial must be in controlled range.
Diabetes and
high blood pressure are the most common causes of deranged renal function worldwide.
With the available described symptoms, there could be possibility of
diabetic neuropathy.
Presence of pain in lower limb could be due uncontrolled blood sugar.
You should consult with internal medicine specialist/
neurologist and should go for thorough neurological check up.
You should avoid Nimesulide as it may cause further deterioration of renal function.
You should also go for serum lipid profile,
electrocardiography, urine routine microscopy, glycosylated hemoglobin (HbA1c).
You should remain in touch with
nephrologist.
Take care,
Dr. Mayank Bhargava
