I am asking about my husband. He has an open sore on his leg that has been there 2 years. It will not heal. We also think he has sleep apnea because he stops breathing while sleeping, and his snoring has become worse over the years. So now, he is tired, irritated, there is a sore in his mouth, as well as the open sore on his leg which is about 3 inches in diameter. He has gone to a primary physician for the open sore, but the doctor would only see him for that one complaint, gave him some cream that did not work, and sent him home.
