I feel there is a big jumbling happening here...Please clarify:
1. Are you saying you have high fasting sugar (105) and your foot condition is pathetic and so you feel you have got this disease- diabetes? Are you asking about boils
and corns in your feet which are making your feet pathetic and hence you have query if you have got diabetes?
2. Are you saying eating boiled corn is ok if you tend to have such a high fasting sugar when you have tendency to have diabetes due to family history of diabetes and you have high BP
and family history of kidney
After you get back, I shall clarify you on your query. Take care.
