HI, THANKS FOR CHOOSING HCM, it is true that diabetes runs in families,and the way the body acts to balance glucose levels with and without medication also have some similarities within family members but age ,diet ,activity,modern medication can help to change such condition so dont get panic the problems you explained points me to poor circulation to lower limbs and neuropathy but the grades and extent of the problem can be assessed only by physical examination. please see to it that you go to a doctor ,(atleast for consultation ,to know what your condition is ) so that if your doctor says you are normal ,the stress will be relieved because stress makes you lose grip over the blood glucose control even though you are given good medication even if you doctor finds that you have a poor circulation ,find out the exent of the problem so that you can plan well spending sleepless nights just causes you harm and nothing else please remember this maintaining strict diet,activity,medication helps you to control the rate of damage to your body will power is what matters(more when you are not financially capable) please donot neglect take care HOPE I ANSWERED YOUR QUERY FEEL FREE TO CONTACT ME FOR FURTHER QUERIES THANK YOU
