Hello and thanks for writing in at HCM
Firstly I want to know that for how much years you are suffering for Diabetes
. The pain may be due to diabetic neuropathy
which usually starts at your age but lot depends on the period of being diabetic. More you have a high blood sugar level which adds up to a risk factor.
As per your concern about purple knuckles these may be related to diabetes but need to be rule out for smoking
related disease like aneurysm
. But it is only possible if you are smoker.
In my opinion its better to consult you endocrinologist
for you uncontrolled blood sugar level.
