my father has diabetes and we got a letter in mail about a month ago and the letter simply stated to my dad to come off the zorcor. because he had elevated muscle enzymes or something to that effect. and he had stated that he had tingling in his arm along with chest pain. my fury is with his diabetes spclst, why couldn't she be honest and tell us that this medication could possible be the culprit of his elevated blood readings. i am very disappointed in this doctor.
