Dear Richard. Welcome to healthcaremagic forum...
of 6.5 for a diabetic patient is good. This clearly points out that she is doing well with regards to the sugar control. Diabetes leading to neurological conditions is common in uncontrolled diabetes
and those suffering from it for a long time.
From where I see, diabetes is under good control. Hence in these circumstances, a thorough physical examination is also needed to look for other causes of numbness
clammy feet. Check if the pulses are felt well (in the affected limb)??
Seeing a doctor will definitely be useful.....
