husband is type 2 diabetic. he has not been good with monitoring. recently developed itchy, red mottled looking skin on the lower extremeties of his legs. when he finally checked BS, it was high. went to his MD..and was told it was a celluitis and put him on a high dose of antibiotic . Made no reference to it having anything to do with diabetes . On day 4 of drug , no change. we are monitoring his diet and have initiated an exercise program and are slowly bringing this BS down. I feel this leg problem may be related to the diabetes, but other causes may be what?
